<example>
   >>> m = lambda:0
   >>> m.myattr = 1
   >>> m.myattr
   1
   >>> _
</example>

But I feel that that is an abuse of the language, and that an Expando class like 
you show is far better.

Thanks for the class name suggestion, by the way  --  I've wondered what to call 
such a class, and now it's clear. :-)
