[erlang-questions] Introspecting the atom table

[Eric Merritt]

Guys,

 Is there anyway to introspect the atom table? I would like to be able
to take a string and check if that string has been interned in the
atom table. Even better would be a bif that converts the string to an
atom if that atom already exists and doesn't otherwise. I suspect that
this type of functionality doesn't exist, but I thought I would ask
and make sure.

Thanks,
 Eric
