Oh, this is what I missed. For cases like this, I tend to create an unexported package variable that's initialized with MustCompile. package-level variables are generally bad-form, but there are cases where you have mostly-readonly things that must be initialized at startup in which they make sense. (constant-initialized regexps are one of these) Which is why I was trying to not use them or make things const. Long ago, when dinosaurs roamed, I spent a lot of time trying to use C++'s const in places that made sense. It was a disaster and I gave up. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
