Hello all,
I have a challenge, which is this: I'd like to have a public property which will
return a reference to an internally stored class instance.
ref MyClass myProperty() @property
{
...
}
However, this runs into a problem: I can't use "static" to internally store a

In any case, I think class static this is the solution:
I think I may have misled you by talking about properties, because I _don't_
mean a property of a class. I mean a public standalone function that is marked
as a @property, which returns a persistent

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.

It's still essentially a singleton - it's just that it's a single instance per
thread in that case instead of per program. And you avoid all of the
threading-related initialization issues with singletons if it's thread-local.
Just check whether it's null

Yeah. Something like that.
What I like is that it actually comes out slightly nicer than the existing code
-- you don't need an extra static boolean to check if the RNG has been
initialized. This experience is proving typical of class-based RNG and

A lot of dmd's error messages aren't great.
Would this be better?
Cannot initialize thread-local class variable %s with a mutable value.
Only const or immutable initial values are allowed (e.g. null).
That would be better.

The changelog is partially generated from Bugzilla issues. That was the main

Fair enough :-)
