I will write with several elsif statements one for each value of the array

Surely you're missing something here, why not run a foreach on the array and in that test the values, or try another thing? What you describe sounds so very un-programmatic, that I suggest reviewing the logic flow of the program at that point, and see how it could be generalised into a loop.

You've been shown a number of solutions already that make what you suggest unnecessary. There are other solutions too, if you cared to elaborate on the context.

I did have doubts about it being possible.

Of course it's possible. As several wise monks have pointed out, it's also a Very Bad (and rather pointless) Idea unless you are in contention for the Jerk of the Year award from your fellow programmers, especially those who will have to maintain your code after you 'leave' (read: 'get fired for doing stuff like this').

But it's possible:

>perl -wMstrict -le
"my @pmis = qw(foo bar baz quux);
 if (do { for (@pmis) { if (/(.)\1/) { print; } }  1; }) {
   print q{well, that's done};
   }
"
foo
quux
well, that's done
