in reply to Re: Regexp optimization - /o option better than precompiled regexp?
in thread Regexp optimization - /o option better than precompiled regexp?

"The /o option means that the regexp is interpolated and compiled only once for the complete life of the program."

But why then is main::CORE:regcomp still being called on every iteration, just as in the cases without /o?
