Writing
class Foo
{
shared Foo a;
static Foo b;
static shared Foo c;
}
`a` is an instance-local shared reference. `b` is a thread-local not-shared
reference. You would expect that `c` would be thread-local shared reference -
but instead it's a process-global shared reference.
I do not suggest changing the behaviour of `static shared` - it is the syntax
for process-global shared variables by design, and changing it will break too
much code. But we do need a way to create thread-local shared variables.
I've implemented a library solution, but I believe this problem requires a
compiler solution that's why the component field is "dmd".
