The snippet below failed to compile (I think) in the latest DMD - 
but I can't see the error message in the web-based editor at 
dlang.org. It certainly failed to compile under GDC 5.2.0 when 
tried out using d.godbolt.org. (Is there any chance of a later 
GDC compiler there?)

Is it my bug, or a compiler bug? (name clash at link-time?):

void main()
	{
		{
		immutable static dstring str1 = "a";
		}
		{
		immutable static dstring str1 = "b";

	}

Workaround is just to rename one, assuming that avoids a name 
clash at <xx?phase>-time.

Well, based on the error message, I'd say that the restriction is on
purpose:

q.d(7): Error: declaration q.main.str1 is already defined in another scope
in main

The bit about "another scope" just wouldn't make sense if it weren't on
purpose, since there is normally no such restriction. That being said, I
have no idea why such a restriction would be in place. It works perfectly
well if the variables aren't static, so it's something about static that's
causing it. I would argue that it _should_ work, so I think that you should
at least open up an enhancement request, but I have no idea what the
compiler devs would say on the matter.

Ideally (imo), the code would work. The two variables would need 
different mangled names. No idea how hard that would be to implement.
