                 options, of course ;)

Well, yes, that's supposed to work, but I simply do not feel it's as
pretty as other parts of Ruby.  I mean, I just couldn't explain why
"proc(a, b, *c)" is allowed and "proc(a, *b, c)" or "proc(a, *b, *c)"
is not, considering Ruby's consistent nature.

Is it hard to implement that, or does it decrease Ruby's cleanness in
any sense? (I'm not pushing so hard, but just curious :)
