I do prefer not to make it possible to extend the language, thats why
the explicit syntax:
  {$Macro mac(params)}  and
  {$Expand mac(params)}
I think that completely encapsulates the text manipulation from the
  language level.
True, if used the readability will suffer. But at least you see
  that it happens (You know there is a hidden piece of whatever, thats
  not that far away from looking of a procedure call and not knowing
  what that function will do. If you are interested in details, look at
  the source. The same with an macro).
