You should at least use it in for loops. It's a useful improvement, and especially handy in combination with type inference. For example:

  for var i := 1 to 10 do
    Inc (Total, i);

i is declared inline, it's only in scope inside the for loop, and the type is inferred from the bounds of the loop. You could of course use "for var i : Integer := 1 to 10 do" if you wanted to be explicit about the type.
