Of course. 'auto' was a bad idea. Either 'end', 'var' or some other
reserved keyword is preferable.

But also force lower bound to be always zero.
IMHO this is unnecessary restriction, although it might be ok
if implemented in addition to the auto-calculated upper bound.
I think having to write arr: [0..var] of Integer will not make porting
much harder,
especially compared to the horror of manual counting required now ;-)
