[Python-Dev] Not backporting PEP 3115 (metaclass __prepare__)

[Jack Diederich]

We can't backport the __prepare__ syntax without requiring metaclass
definition on the 'class' line.  Because the __metaclass__ definition
can be at the end of the class in 2.6 we can't find it until after we
execute the class and that is too late to use a custom dictionary.

I wish I had thought of that yesterday,
