Not sure why this comment is in the commit message, but FWIW, I tend to
disagree: it's usually preferable to keep the macro part to a minimum
(handling the syntax), and to keep as much as possible in functions.

There's no hard&fast rule, tho.

I see, thanks.  I tend towards macros that expand to efficient code and
eliminate runtime dependencies; however, like all things it's a trade
off, be it code size, macroexpansion speed, etc.

Part of the issue for me is to hardcode a particular behavior.
Going through a function makes it much easier to change the behavior
after the file has been compiled.
