In any case, I think class static this is the solution:

returns a persistent instance of some class.
The actual motivation is reimplementing std.random.rndGen but
with class-based RNGs instead of structs :-)
A consequence of this is that I don't think a static class
instance can work, because the returned class has to be
non-const -- it's an RNG that will be updated!
I understand you are talking about the "Singleton" design pattern.
You might want to look how std.parallelism does it with the
default global thread pool.
