Re: problem with variables

[Brent Michalski]

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...
