Well, for 1-based arrays it would be
for i := 1 to someexpression.count
(without the annyoing -1).
In general I can make sure that somexpression.count is zero or larger
when I use it to determine an index for my array.
The same would be
for i := low(array) to high(array)
which is very common and where I would not need to use an unsigned integer.
