Would adding a runtime parameter improve the API?
Well that's a good question: I'm just thinking out loud really, the options are choice or no choice, and if choice then compile-time or runtime? My gut feeling is that compile time parameterisation should be used only when there's some real benefit, and I don't see it in this case - there's no need to make everything a template :-) No honestly there isn't really :-> The reason I threw this one in, is that there was a suggestion (from Kevlin Henney's thread proposal if I remember correctly) to decouple thread object creation, from the actual execution of the thread, so that then we can tweak the threads properties with getters/setters before we execute the thread (think thread priority, scheduling policy etc). Does this make sense or am I barking up the wrong tree? John.
