This piggybacks off the defmacro + infrastructure which we now have. + + - Big improvement in debuggability: the unhandled exception error message now + gives source code location information. + + - New functions pos, pos-if, posq, posql and posqual for finding item + positions in sequences. + + - Predicate function is now optional in the some, all and none functions. + + - hash-uni and hash-isec functions take a join-func argument which + lets you specify how elements from two tables are merged. + + - new hash table functions inhash and hash-update-1. + + - two hashes can now be tested for deep equality using equal. + + Bugs + + - Removed bogus optimization from hash table implementation. + + - Syntactic fix: input like 1.0a no longer parses as a floating-point number + followed by a symbol, but is diagnosed as an error. Syntax like 123a + continues to work as before: it denotes one symbol, not 123 + followed by a. + + - Bugfix in type check for "cobj" class objects that would crash if + given non-heaped values like fixnum integers. + + - Corrected problems in the code walking and expansion of lambda and + defun forms. + + - Fixed failure to propagate line number info through the abstract syntax + of string quasiliterals. + + - Doc bugs: missing descriptions of gethash and gensym. + + + TXR 79 2014-02-11 |
