I was inspired by your map example to do something like this instead:
$value=" 1 ";
@array=map {$_=$value} (1..100);
$i=0;
foreach (@array) {
print "$i $_\n";
$i++;
}

The $i variable (used as an incrementer) and the foreach merely proves the map statement.

    You can eliminate the $i var by doing the following:

    for (0 .. $#array) { print "$_ $array[$_]\n" }

    Also, I would think you'd be better off using one of the other suggestions like for() or the x operator rather than map() for efficiency reasons.

      I like that... very clean, to the point, and quite readable. The only reason I chose map was to flex an all too atrophied brain muscle. :)
