Thomas Wouters <[EMAIL PROTECTED]> added the comment: Updated patch: reworked some internals, and added generalization of functioncalls after talking with Guido. *args is now considered just another positional argument, and can occur anywhere in the positional argument section. It can also occur more than once. Keyword arguments now have to appear after *args, and **kwargs can now occur multiple times at any position in the keyword argument list. test_extcall has some examples.
(The opcodes are largely unaffected; just the order of '*args' and keyword arguments is changed. Behind the scenes, anything after the first '*args' argument is collapsed into a single *args, and everything after the first '**kwargs' is likewise collapsed. The common case (meaning any currently valid syntax, barring the 2to3 fix to swap *args and keyword arguments) does not change in meaning or codepath, just the complex cases are handled differently.) This is still Work In Progress. To do: implement the dict unpacking syntax (the mechanics are already there for keyword arguments to functioncalls), make sure the precendence of * is correct, get more complete test coverage, iron out the cosmetic bugs in the 2to3 fixer. Bzr branch for this patch is http://code.python.org/python/users/twouters/starunpack . There is also a branch with just the functioncall changes (although the starunpack changes are a small sprinkling on top of that branch, as it uses the same new mechanics): http://code.python.org/python/users/twouters/funcargs .
