Need Help??

in reply to Regexes and /o

What version of perl are you using? In recent versions (5.6.0 and later I believe) the penalty for not using /o was greatly reduced.

So, /o isn't really much of a gain anymore because the worst case scenerio it was designed to avoid is no longer applicable.

Yes! Precisely! And since you can use qr// for when you want maximum speed and maximum control, there is no reason to ever use /o. Ever!

It should be deprecated from the language because the best it can do now is provide a slight speed boost (which you can still get by using qr// instead), but the worst it can do is break your code.

Most of the times I see people use or recommend /o these days are cases where it makes absolutely no difference at all, or where it breaks their code.
