I have changed my mind on this issue. Since

e = 1
del e
def g(): print(e)

compiles and raises a run-time name error, so should the same code embedded within a function. In either case, the premature deletion is a logic error, not a syntax error.

However, changing the language definition, even to fix what is considered a design bug, is a feature request. For both 2.7 and 3.1, section 6.5. "The del statement", says "It is illegal to delete a name from the local namespace if it occurs as a free variable in a nested block."

So this seems too late for 2.7. On the other hand, Guido has allowed it for 3.2 in spite of the moratorium, but I think it should go in the initial release.
