As with everything, it's just a matter of someone implementing it. Although, if
"__thread" and "thread_local" have different semantics, I wonder what syntax to
use in D then.

// foo.cpp

__thread int a;
thread_local int b;

// foo.d

extern(C++) extern int a; // this will have the semantics of __thread
extern(C++) extern /* __thread_local ? */ int b; // what should this syntax be?
