In the existing language, I think version (or static if) at the 
usage and definition points both is as good as you're going to 
get.

unless you use a preprocessor lol

But the good news about version is you could use compiler errors 
about missing name to know where it needs to be (unless there's 
another matching overload in scope[!]). So it would be mildly 
verbose to look at in the code, but not really difficult to get 
right (and you could write it with autocomplete, like vim's 
`:abbr foo version(foo) foo`).

That'd be kinda tricky because the arguments would still be 
liable to be evaluated... so the intrinsic would need to cover 
and disable that too and I think you'd be in for a fight to get 
that approved.
