Not having to hack around this would be nice. http://bugs.python.org/issue15627
AST transformation is a lot more general than just optimization. Adding an AST transformation is a relatively painless way to add to Python the last element of lisp-ness that it lacks: Namely being able to treat code as data and transform it at runtime, after parsing but before execution. Some examples: Profiling code be added by an AST transformation. IMO this would have been a more elegant way to implement CProfile and similar profilers than the current approach. AST transformations allow DSLs to be implemented in Python (I don't know if that is a + or - ). Access to the AST of a function at runtime would also be of use to method-based dynamic optimizers, or dynamic de-optimizers for static compilers. All for the price of adding a single method to SourceLoader. What a bargain :) Cheers, Mark. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
