I've got a situation like this:

struct A
{
  opEquals
  int idx = -1;
}


class Foo(Type)
{
   ...
   static const A  StaticA;
}


But it doesn't work when I try to do something like this in a function:


   A myA;

   if (myA == Foo!(Type).StaticA) { // <-- error here
   }

The error I get is:
   Error: can only initialize static const StaticA inside static constructor

Is this a bug?
I notice that it compiles if I make StaticA just "static" instead of "static const".

At the very least the compiler error text seems wrong since I'm not trying to initialize anything.

Is StaticA getting initialized somewhere?
If not, that's probably the root cause (and the error message is a bit misleading).

It's not getting initialized anywhere, but it's a struct, so it has a default value with which it should be implicitly initialized.

Are you saying that I should be doing
    static const A StaticA = {-1};
?
I'll give it a try, but it doesn't seem like that should be necessary.
