I might, if it weren't for the redundant "if" and the horribly buggy
interference between separate instances -- which is why I wrote it,
almost six years ago and without the bugs, as
<http://aspn.activestat e.com/ASPN/Python/Cookbook/Recipe/52308.

Nice one. I gotta dig up the Cookbook again.

You make a good point. I do like being able to say foo.bar=baz rather
than foo['bar']=baz in certain cases -- not so much to save 3 chars, but
to avoid excessive punctuation; however, I don't really need this AND
all of dict's power at the same time, so, I don't inherit from dict:-).

Yes. Attribute syntax looks nicer, in particular one implements a sort
of private "variables collected in a dict" thing (e.g. SQL field names)
but still wants some dict functionality.

Another variant I thought of would be to prefix dict methods with '_'
(except those that already start with '__') and (if implemented as a
dict subtype) also override the original names with a "sorry, use
_<foo>" error method.
