I tried something like s///ge at one point, but it doesn't work in this case. The /e causes the right hand side of s/// to be handled as code to eval. Well, since we are deliberately matching Perl code with this regex, this solution tends to choke quite spectacularly.

I think its probably cause your substituting stuff into content, making the string different when it tries to do a second match...

Oh!!!!! Good point. Didn't think Perl would bomb on that. Need to go check it out. Thanks.

Update: Oops. Just noticed that tye pointed out the same problem and I've verified that it's the bug. Here's a bit of sample code that can reproduce it (don't do this at home, kids): 

#!/usr/bin/perl 

$string = "1";

# Infinite loop caused by modifying the string we are matching against
+ in while statement

while ($string =~ /(\d)/g) {
    $match = $1;
    $string =~ s/$match/$match/;
}
print $string;

Update 2: After reading through Boogman and tilly's comments below, I'll have to see what I can do to reproduce the /e error. It was rather frustrating.
