Several people have told you that this is incorrect.  I'm not sure
that you understand why.

I'm not aware that there's anything actually *wrong* with your code
in the sense of violating any language rules.  The point is that
most of us will not bother reading code that uses those silly little
macro definitions.  They make the code more difficult to read, and
it simply isn't worth the effort to mentally translate R to return
and F to for as we're reading it.  You save yourself a few keystrokes
at the expense of clarity for anyone else reading your code.

If you want anyone to read  your code write it more clearly.
(And that doesn't mean "more clearly for *you*".)  If you are unwilling
to do that, you can write whatever you like, but you might as well not
bother to hit "send".
