That's pretty much the canonical example. Only thing I'd do
is twink around with the rigging, e.g.
my( $max, $key, $pad ) = @ARGV;
print $key, $pad x ($max - length($key));
My own thoughts tend toward the following:
$_ = $pad x $max;
substr( $_, 0, length($key) ) = $key;
print;
But I can't shake the feeling that that second line
could be shortened, perhaps by using s/// cleverly...
