Cool.  I usually don't use the index value either.  But it seemed best to
keep the symmetry with the existing for-in table syntax, and use _,v to
throw away when necessary.

I looked at sol a little a while ago; I was impressed.  I'm a little worried
about how far it is away from straight lua, but that's more a
political/social issue than a technical concern.
