I like to solve logical puzzles, so I loved to come up with a 'solution'

Unfortenately, there are too many situations that the parser can't control with a Macro substitution, personally I would not try to bother. For instance your code looked like a 100% winner for producing an error but it wasn't. But what if the parser insisted it was a 100% faillure, no thanks.

And I think that all the others are correct, only use Macro substitution only when needed. A lot of times, there are better alternatives.
