Need Help??

in thread Ternary Operator with Subroutine

There must be something I didnt understand yet, so I excuse my question, dear Monks. But why would anyone ~~would~~ like to do that? Is there any possibility, that

my $test
[download]

may fail?

It seems to me like writing

if (1) {
   print "some";
} else {
   print "thing";
}
[download]

(And in that case, I could imagine some kind of debug-switch or so).

Please enlighten me.

Is there any possibility, that my $test may fail?

Actually, it will always "fail". That is, an uninitialised variable is always undef, and therefore false.

It also doesn't make much sense to do print 'a'; print 'b'; instead of print 'a', 'b'; or print 'ab';.

I think it is fair to assume that the code supplied it greatly simplified example and that ( my $test ) is just a placeholder for 'some boolean condition' rather than an actual variable declaration.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
