Mark Dickinson added the comment: It looks like fixing the production list is the easy part (see attached patch): as far as I can tell, the *syntax* for class definitions is pretty much identical to that for function calls. (The semantics are different, of course.) It would be good if someone could check this patch for sanity, though. The description in that section still needs updating. ---------- keywords: +patch Added file: http://bugs.python.org/file17802/issue9117.patch _______________________________________ Python tracker http://bugs.python.org/issue9117 _______________________________________

Mark Dickinson added the comment: Yes, good plan. I'll do that. I'm also not sure about the 'comprehension' bit; it's true that a comprehension is syntactically valid here (e.g., "class A(x for x in range(3))"), but it's also entirely useless: it has to be the sole argument, so there can't be a metaclass argument, so the metaclass would have to be type. But type (quite sensibly) won't accept a generator as a base class. Oh well; I suppose it doesn't *have* to make sense to be valid syntax... This still leaves the hard part, which is distilling the essence of PEP 3115 and adding it to the reference manual. ---------- _______________________________________ Python tracker http://bugs.python.org/issue9117 _______________________________________

Mark Dickinson added the comment: And the same patch, but this time *without* the irrelevant audioop changes. :) ---------- Added file: http://bugs.python.org/file17806/issue9117_v2.patch _______________________________________ Python tracker http://bugs.python.org/issue9117 _______________________________________

Georg Brandl added the comment: This patch was mostly out-of-date since PEP 3115 metaclasses are now documented; I've merged what was missing in r85626. ---------- nosy: +georg.brandl resolution: -> fixed status: open -> closed _______________________________________ Python tracker http://bugs.python.org/issue9117 _______________________________________
