We're supposed to be able to do this somehow. I think I've seen it somewhere, but I can't find what I think I remember. Mostly I want to see how the compiler interprets code.
Along with decompiling, is there a way to watch what it's doing as it compiles? I think seeing what's it's trying to do and where might be easier than trying to understand some of its error messages. And, decompiling a program can undo all the shorthand and cleverness to elucidate what's actually happening.
