Well, it's not there yet. That being said, I don't particularly like the overloading of `!=` there. I like the idea of a shortcut meaning "call this function and get the error value", but I wouldn't use `!=` for it. Perhaps take a page from Lua's book and use `_` as a throwaway variable. So `a = foo()`, or `a,b = foo()`, or `_,b = foo()`.
