You can if you do it like this:

    my $x = $expression ? true_sub() : false_sub();

    sub true_sub {
        . . . do stuff . . . .
    }

    sub false_sub {
        . . . do stuff . . . 
    }

$x will contain the return value of whichever subroutine runs, which value
$you may or may not care about.
