Well, from the sounds of it, the basic double-checked locking pattern would
work just fine with a shared variable if shared were fully implemented, but
since it's not, it doesn't work right now. So, I don't know that we need to do
anything other than finish implementing shared.
I meant something higher level so you don't even have to think about
double-checked locking. Something like this:
AssignOnce!(shared MyClass) c;
c = { new shared MyClass }; // the delegate literal is called only the
first time
c.blahblah(); // c is guarantied to be initialized at this point
...or something similar.
