Because it messes up what the OP was trying to do, which is not necessarily
something to feel good about.

Yes, we definitely feel good about this, because we don't *want* parameter
support in FPC's macro handling.

What the author wants to achieve here can also be done using a procedure
marked as inline. As long as the unit containing the procedure is rebuild
when assertions are enabled or disabled everything will work as expected
and even the whole call will disappear if it isn't needed. Much cleaner
than a preprocessor.
