If I were a betting man, I would venture that you could post
a recipe for closed_range(), publicize it on various mailing
lists, mention it in talks, and find that it would almost never
There's nothing wrong with the idea, but the YAGNI factor
will be hard to overcome. IMO, this would become cruft on
the same day it gets added to the library.
OTOH for numerical applications, there is utility for a floating
point variant, something like linspace() in MATLAB.
