Re: [FishMonger] single to double quote conversion

I changed all the looks stuff, and did this:

 $regexp = qr/$regexp/;

which as I understood you meant. Of course this works well, and supposedly improves my scripts performance by preventing recompiling the string I get into regexp every time a match is attempted, but I can't see how I can solve my problem with qr. Unless I'm still missing something all it does is compile a string into a regexp, but when I'm doing a substitution:


while $regexp is supposed to be a regexp, and if it's a string it will get compiled to a regexp, but $string is supposed to be a string and not a regexp, and it's $string($changeto in my script) being treated literally that I have troubles with. How can compiling something to a regexp help?
