[New-bugs-announce] [issue3963] Problems when calling exec from a function

[Erik Sandberg]

New submission from Erik Sandberg <sandberg at virtutech.com>:

When an exec statement called from a function f defines a top-level
function g, the body of g cannot access the top-level symbols defined by
the exec statement (which also happen to be the local variables of f).
Example:

x = 2
def f():
    exec "x = 1\ndef b(): return x"
    print b()
f()

An unqualified guess is that the mix of being top-level and being a
local variable, makes the symbol end up somewhere between locals() and
globals(). Example:

The problem causes real-life problems when I want to create a wrapper
function around execfile() to handle certain exceptions.
