It's not so easy because v is of subrange x..y where x and y are more
complex constant expressions. So I would have to check that with a lot of
{$if } to decide between short and small. Makes it also unreadable.

I'm already doing that (now).
With some accustomization, "inc(..." and "v := v + ..." is both good
readable, and normally (at least with checks off) it was assumed to produce
compacter and faster code. Especially when v is not a simple variable, but a
more complex one, e.g.:
Inc ( v[j]^[k].a[l], delta ) ;
And in such a case it's also better readable.
