Everyone I’ve seen who’s interested in this (myself included) is using
these ranges for another reason, to indicate a range of acceptable (or
maybe even unacceptable values). A range like 5…Infinity is not
intended for iteration, but for comparison.5…Infinity is not 5…nil. I think it’s also not a
5…some_number_to_be_determined_in_the_future. I guess that’s the
point I was trying to make. It violates the generic least common
denominator practice present not only in the language, but also its
OK, this last bit sounds a little harsh because I didn’t clarify that
the least denominator thing is actually a benefit.
My first post sort of showed how you could use array indices as open
number ranges. Maybe, we could use a class word Interval instead of
OpenInterval or Range? I’ll turn to whatever direction works for most
people, but I would like some semblance of a solid interval (i.e. left
and right sides).
