Well, #declares and #macros are processed first, that is why they can be
inserted everywhere with very few restrictions.  The parser cannot know
something has been subsituted by either a macro or a declared value because
that is exactly the point of these directives.  They build the scene the
parser reads.  It is similar to not being able to declare keywords as names.
Function parameters behave just like user defined keywords would in this case.
