"as" is coercion - so to what would it coerce? Int or Str? How could the
compiler know? Or do you mean something like a tuple?
I think he wants something like:
------------------------------------------------------------
sub example( -> Int, Str) {
...
return(3, 4);
}
my($a, $b) = example();
$b.isa('Str') and say "b is a string"; # says "b is a string"
------------------------------------------------------------
...and hasn't learned the p6isms that express that. In other words,
he wants to return multiple values, but enforce certain types on them.
