compound conditional

| Can I create a compound conditional with the :? shortform?
I tried putting two statements in curly brackets but that didn't work.
I ended up using if-then but I didn't want to take up much source room
(it only sets a variable to "is" or "are" text :-)).

Yes.

If you show your code we can help fix your code.
If you don't, we can't.

You can't just make shit up and expect the computer to know what you mean.

my $to_be = singular($txt) ? 'is' : 'are';

Yes, I can.
