Generally, altering the contents of the dicts returned by locals() and globals() is unreliable at best.
Nick, could you please comment on why you say this about globals()? I've never heard of any possibility of "unreliability" in updating globals() and, as far as I know, a large body of code exists which does in fact rely on this -- much of mine included. ;-)
