With Neal Norwitz's help, I've developed this patch
which implements the with statement from PEP 343.  I
still need to flesh out the documentation, and the and files (copied almost
verbatim from the PEP) are very bare-bones, but the
with syntax itself is accompanied by a rather extensive

Most of the patch reflects changes in automatically
generated files.  The most extensive changes were in
Python/ast.c and Python/compile.c, and the test resides
in Lib/test/

I'm very open to comments and suggestions, particularly
with regards to the contortions in compiler_with() in

Also, a few questions regarding the PEP itself:

- Should the grammar be strict about not allowing
extraneous parentheses around "(NAME)" in the
with_var_name rule (Grammar/Grammar)?

- Should "(NAME ,)" (note the trailing comma) be a
valid VAR list?  Compared with the rule for global, the
current definition seems to suffice, but (according to
Neal) seems inconsistent in the light of typical tuple

- Should VAR names that are not instantiated prior to
the with statement exist after exiting the scope of the
with statement?
