Idea for 'documenting' unused values

Any thoughts about this idea...?

I created an include file (ign.e) that contains ...

 without warning
 global procedure ignore(object x)
 end procedure
 with warning

then use it like this ...

 include ign.e
 function Foo(integer a, integer b)
    ignore(a)
    ignore(b)
    return 0
 end function
 ignore(Foo(12,2))

In other words, whenever you want to tell people who read your code, that
you are deliberately ignoring a value (eg. a parameter or function return),
you just wrap it inside 'ignore()'.

I *know* it adds the overhead of a useless call, but maybe that's worth
it in the long run. It would be nice if this functionality was built-in
to the language/interpreter.
