No, the -ple causes it to write the code like this:
$\ = $/;
LOOP:
WHILE (<>) {
s/|(\d)|length(9 x $1)|eg;
}
The g on the end of the regex causes it to apply the pattern multiple
times. The e on the end of the regex makes it treat the replacement
like code instead of a string.
Whoops, that should be
$\ = $/;
LOOP:
WHILE (<>) {
chomp;
s/|(\d)|length(9 x $1)|eg;
}
