Actually is there an opportunity for some kind of language enhancement there? I do not really know what I am talking about AT ALL but if the compiler could silently add an extra specialisation that gets generated at compile time, with constant folding and all the optimisations that follow from it, if a call with an appropriate constant argument is seen? But this is probably horrible because that kind of stuff is ph performed at a completely different point ?
