Good point however I was more asking the question of:
"Does it make any difference speed wise or logic wise to ask if a match is true or a match is false in an if statement?"

I dont think I have ever had an issue with the speed at which Perl does things. Blindingly fast is good enough for me :-)

I like giving my variables nice descriptive names and making my if elses open and legible - especially if I expect someone else to pick up the code and do something sensible with it :-)

I guess I'm remembering the old BASIC days when CPUs were slow and it mattered how things were done.
