Ouch!  Emile, stop doing that.  Use

    exec a.func_code in {'b': 4}

It isn't, and is therefore undefined.  Before Python 1.0, "exec" was a
builtin function rather than a statement.  The ancient function form is
still accepted for backward compatibility, but that's been a secret <wink>
for nearly 8 years.
