I think it is widely agreed on that all these static checkers (e.g. for 
totality of functions) fill the gap of a type system that is not strong 
enough to handle these cases. Have you ever tried one of the 
units-by-types libraries so far? They catch many bugs and are already 
quite natural in usage.
