about return

[terry peng]

hello,

when in the case "return undef" I prefer just "return" coz in list context it 
will return an empty list.

my $exist = ...
if ($exist) {
    return 1;
} else {
    return;
}

the code above can work, but having many lines.
So I want:

return $exist ? 1 : (...);

what should be put in (...) to get the same effect as just "return" (not return 
undef)?

regards.
