The same can be said of any language that lacks a rigorous definition; misusing -Ofast is just an example of one. Even then, the definition can be too large or tricky for anybody to truly understand, but that's a bit of a grey area... at some point you have to draw the line and say the programmer made a mistake. The only sensible thing to do is draw the line at the definition of the language, otherwise there is chaos.
