diff Python/Python-ast.c @ 41226:19f7ff443718

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Implement PEP 3115 -- new metaclass syntax and semantics. The compiler package hasn't been updated yet; test_compiler.py fails. Otherwise all tests seem to be passing now. There are no occurrences of __metaclass__ left in the standard library. Docs have not been updated.
