the sequencing! Making it an inline function broke the tests.
But we can't have multiple evaluation either, so it's going to use
a temporary lexical variable.
(uses_or2): Macro which declares the lexical variable needed by or2.
* debug.c (debug): add uses_or2.
* eval.c (eval_intrinsic, op_modplace): Likewise.
* lib.c (lazy_str, lazy_str_force_upto, lazy_str_get_trailing_list):
Likewise.
* match.c (h_parallel, v_freeform, v_parallel, v_output): Likewise.
* parser.y (unquotes_occur): Likewise.
* stream.c (format): Likewise.

increment value. Separate new value and increment value, and check
number of arguments.
* lib.h (or2): Turned into inline function due to multiple
argument evaluation.

(op_dohash): New static function
(expand): New case for dohash_s.
Bugfix for do_s: expand was used rather than expand_forms.
(eval_init): dohash_s initialized and entered into op_table.

* hash.c (maphash): New function.
* hash.h (maphash): Declared.

of the form var, only (var initform).

* eval.c (car_s, cdr_s): New symbol variables.
(op_modplace): Cases for car and cdr added.
(expand_place): Likewise. Calls abort should the
cases fall through rather than returning 42.
(expand): Bugfix: for and for* case not propagating
source location info. Bugfix: expansion for do added.
(eval_init): car_s and cdr_s initialized and used
in place of previous intern calls.
* parser.y (elem): Removed wrong logic for expanding the
do form. It was expanding only the first argument.

(env_replace_vbind, bindings_helper): New static functions.
(op_let): Refactored to allow for let* form. Code for setting
up bindings moved into bindings helper, shared by for loop.
(op_for, expand_vars): New static functions.
(expand): Bugfix: let case was neglecting to walk the var
initialization forms. This is done via expand_vars now.
let_star_s added to this case to handle let* and let at
the same time. New case added for for and for*.
(eval_init): let_star_s, for_s, and for_star_s initialized,
and entered into op_table.

* eval.c (op_let): Bugfix: was not evaluating var init forms.
(reg_var): New static function.
(eval_init): Registered numerous stream functions and the
three standard streams.
* lib.c (obj_print, obj_pprint): Modified to return a value.
(init): eval_init called after stream_init, because eval
needs the three standrad streams prepared.
* lib.h (obj_print, obj_pprint): Declarations updated.
* stream.c (format): Support t as a shorthand for standard output.
(formatv, open_directory, open_file, open_pipe): New functions.
(w_opendir): New static function.
* stream.h (formatv, open_directory, open_file, open_pipe):
Declared.
* txr.vim: set iskeyword such that keyword can contain special
characters. Set b:current_syntax to "lisp".
(txl_keyword): New keyword category populated with TXR Lisp keywords
defined as separate category.
(txr_list): Contains txl_keyword.
(txr_meta): Contains txl_keyword and txr_list.

fun operator.
* eval.c (apply_s): New symbol variable.
(apply): Handle functions specified as symbols. Use symbol from context
form in error reporting.
(apply_intrinsic): New function.
(interp_fun): Bugfix: removed evaluation of arguments, since
arguments are already evaluated.
(op_call): Simplified by not having to handle symbols,
since apply does.
(op_fun): New function.
(expand): Handle special form fun.
(mapcarv, mappendv): New functions.
(eval_init): Initialize apply_s. Register op_fun function
in op_table. Register mapcar, mappend and apply functions.

New functions list, append and eval. Code walking framework for
expanding quasiquotes. quotes right now.
* eval.c (let_s, lambda_s, call_s, cond_s, if_s, and_s, or_s
defvar_s, defun_s, list_s, append_s): New symbol variables.
(eval_intrinsic, op_quote, expand_forms, expand_cond_pairs,
expand_place, expand_qquote): New static functions.
(expand): New external function.
(eval_init): Initialize new symbol variables. Use newly defined symbol
variables to register functions. Also, new functions: quote, append,
list and eval.
* eval.h (expand): Declared.
* lib.c (appendv): New function.
(obj_init): quote and splice operator symbols moved into system
package.
(obj_print, obj_pprint): Support for printing quotes and splices.
* lib.h (appendv): Declared.
* match.c (do_s): New symbol variable.
(syms_init): New variable initialized.
(dir_tales_init): New variable used instead of intern.
* match.h (do_s): Declared.
* parser.y (elem): @(do) form recognized and its argument passed
through the new expander.
(o_elem, quasi_item): Pass list through expander.
(list): Use choose_quote to decide whether to put
regular quote or quasiquote on quoted list.
(meta_expr): Fixed abstract syntax so the expression is a single
argument of the sys:expr, rather than multiple arguments.
(unquotes_occur, choose_quote): New static function.

* hash.c (struct hash): acons_new_l_fun function
pointer order of arguments change.

(acons, acons_new, acons_new_l, aconsq_new, aconsq_new_l): Reordered
arguments for compatibility with Common Lisp acons.
(obj_init): Special hack to prepare hash_s symbol, which is
needed for type checking inside the hash table funtions invoked
by make_package, at a time when the symbol is not yet interned.
Initialize new env_s variable.
(obj_print, obj_pprint): Handle ENV. Fix confusing rendering of
of function type.
