The new ranges are an improvement, but...
I find the fact that <high>-<low> must be divisible (the error message
says divisable which is a misspelling) by <inc> to be slightly
annoying. I had in my code thinks like:
to specify the odd integers smaller than n, and
to specify the even integers less than n. I hoped to be able to rewrite
[1,3..n] and [2,4..n]
but the first one works only for n odd and the second for n even!
One has to use
[1,3..n-1+(n mod 2)] and [2,4..n-(n mod 2)]
which is less pleasant and efficient.
What is the rationale for the restriction?
