Also, Pascal is all about readability and maintainability, so avoiding
a redundant variable declaration and attribution, and the opportunity
of people misusing and mis-reusing a counter variable is pretty worth
IMO.

It's almost necessary, if you want to implement real safe code and
don't wanna use tens of units.

Indeed, not much, but the memory savings can be really interesting in
some situations.
