Hmm, where did I mention Pi or cosines anywhere in my answer?

I am simply trying to help out beginners and tackle common programming
tasks that can be done in more of a Perl-ish way.

If you want to show a way to do something more complex, please do so.  If
you just want to be a smart-ass, please save it for a different list.

So your saying that Perl can handle calculating cosine while iterating
through Pi?

for my $inc (-3.14159 .. 3.14159)
{
           push @result, cos($inc);
}

Come on... C style for loops have their place.

To add to the answer(s) already given...

for ($i=1 ; $i<4 ;$i++){
    print $sup($i);
}

is actually quite cumbersome, and very 'C'-ish...  Let's make it more
Perl-ish...

for my $i (1..4){
  print $i;
}

There is not need to have to deal with incrementing and checking conditions
in loops - Perl does this very nicely for us already...
