But I don't need to run my code on that hardware. I need to run my code on a particular subset of hardware. I don't want the programming language that I use the most to tell me that I can't have the features I want because somebody else doesn't have them. "Just because a baby can't chew a steak doesn't mean that a man must drink milk for dinner" There's a half way point: expose directives that say "I'm going to use this feature, so just refuse to compile if it's not available".
