in reply to Auto-detecting returned or passed variable type

Obviously the correct way would be always to pass Function A a reference to whatever Function B returned, but how can I create the reference to it when I don't know what it's going to be?
You don't have to know what it's returning to take a reference to it:funcA(\funcB());will pass a single reference (scalar) to whatever funcB returns.

Update
The note below is correct. Ignore this.

    Not if funcB returns a list. Then funcA would get a single reference to the last item in the list. Not to the whole list.

      Are you sure? 
      $ perl -e "
sub a{return (1,2)}
sub b{print scalar @_,
            map $$_, @_}
b(\a());"
