Summary: Different behavior when stepping through code w/ pdb

Initial Comment:
The attached test case will raise a NameError when
executed in pdb by stepping though the code.  The issue
is the EnumType name, which is both a local variable in
the Enum function which is used in the lambda and the
name of an attribute on the EnumValue class.  Since it
is a local variable used in a lambda, it's a freevar. 
What apparently happens is on line 5 the property()
result is stored in frame->f_locals['EnumType'] but it
is deleted the next time FastToLocals is invoked prior
to calling back into the debugger.  This happens when
the freevars values are merged into the locals dictionary.

The example is a stripped down version of code in
turbogears.
