Yeah, that occurred to me about a half-second after I posted that
response. in...keys() would work but would impose a huge performance
lose. (I try to think a little more carefully when writing code
that I plan to actually run.) The try/except thing looks interesting,
I'll have to study the later comment that it's substantially faster
than has_key().
