What about posting that as a [challenge] on the main D newsgroup?

It's also interesting for floating point values between 0 and 1, for
probabilities or whatever field that's normalized.
Heck, even for defining letters, digits, etc.

alias Ranged!(char, 'a','z') letters;
alias Ranged!(char, 'A', 'Z') Letters;
alias Ranged!(char, '0', '9') digits;
