Introducing global lexicals: defvarl, defparml.
* eval.c (defvarl_s, defparm_s, defparml_s, sys_mark_special_s): New
symbol variables.
(mark_special): Return val rather than void, since it's hoisted
into Lisp domain now with func_n1.
(op_defvar): Renamed to op_defvarl, and doesn't call mark_special.
defvarl is now the special form for defining variables, and special
marking is an embellishment added by macros.
(me_defparm): Renamed to me_def_variable. Handles defvar, defparm
and defparml.
(do_expand): Expand defvarl, rather than defvar.
(eval_init): Intern defvarl, defparm, defparml and mark-special
symbols, and initialize corresponding globals.
Register defvarl special operator, retiring defvar.
Register defparm to me_def_variable, and register defvar and
defparml to the same.
* txr.1: Document support for global lexical scopes and the
new macros.
