Hi,

I just noticed in RadiobuttonsWidget that 'delim' must be specified
at the time of creation, rather than at the time of rendering.  Would
it be possible to provide it and/or override it in render() as a kw
argument?

This comes up because I'm building a reusable library of question types
for a conference submission system, and the creation/loading of objects
is very separate from the rendering.  It seems to make sense to have
arguments that affect rendering associated with the render function,
although I can understand why you'd want them at creation too.

And yes, I'll just put in a change to self.delim in the appropriate place
in my code for now ;).

cheers,
