Hi there,

is the concept of generators (like in Python, using yield) 
available in D? If so, where can I find information?

I do not know python well, but do you search for this one?

Generally speaking, things that are generators in Python are 
implemented as ranges [1] in D. If ranges aren't a good fit for 
your problem, though, you can also use opApply [2] and 
std.concurrency.Generator [3].
