Unless I'm missing something, after several separate discussions on the D IRC,
I could not find a way to run a function 'n' times lazily for a range without
doing hackery's like this:
iota(100).map!(x => uniform(0, 76));
The use case is where you want to repeat an (impure) function n times lazily.
A possible example:
auto five_random_ints = take(recurrence!(uniform!int), 5)
or
auto five_random_ints = repeat!(uniform!int)(5);
If there is an idiomatic way to do this already that I am missing, sorry for
taking up your time.
