Yes I can live without macros too, i do it for years.

FPC has macros today, and the one of the bad way, which you do not see
in the source!! And the scanner is today checking every identifier for
macro expansion, if you switch {$MACRO ON}.

Try to remove the macro support from the compiler and we will see,
there are people around, which use them, even the ones without
parameters.

The way I suggest for macro parameters make them better:
	{$I %name(some text)}	makes it clear, thats a macro
expansion. In respect of readability, where is the difference to:
	name(param1,param2)	in pascal, where you do know
it is a function call. Thats the same.
