[IronPython] NameError: locals() is not defined?

Despite "locals" being involved, 16884 is not a related issue.  The problem
in 16884 is with the delegate that's created for function a and the way
that it's bound to the context in which the function was declared.  And
alas, 16884 is not fixed in beta 3.
