Thanks! There are some usefull ideas here. I'll probably keep things 
simple for the 0.28 release, but I definately see things like tieing it 
into the new options in the next release.

Might possibly go ahead and add the callback; this very much echos the 
options interface. It has a multi-option type, and callbacks via the 
on_validate handler. OTOH, the user could do this via.

my $need_answer = 1;
while ($need_answer) {
   my $ans = $mb->ask(...);
   $need_answer = !valid_answer( $ans );
}

So a handler only adds a little bit of sugar...
