Hmm i wonder... If recognizes it as infinite, could it avoid treating them as forward ranges? As a struct it still wouldn't work, but as a class/reference type it would work then...
They shouldn't be forward ranges anyway, because if their content is randomly generated then it's not legit for them to implement the .save property. The whole implementation of stuff in std.random via forward ranges is a massive design mistake.
Implementing the random algorithms/other wrappers as a class is problematic because then you get into the hassle of potentially having to new/free a lot of individual heap objects deep in the inner loop of your program. I already tried this in hap.random, and came to the conclusion that it wasn't a valid approach.
