Just a small implementation note: I think @nodiscard should not 
apply to void functions. In other words, if I have:

-----
@nodiscard:

int foo();
void bar();
-----

then calling `bar();` should just work, we shouldn't need to 
write `cast(void)bar()`.

At least I can't think of use-cases for it having an effect on 
void functions.
