Thanks Iain.

For Global variables can now be initialized with Associative Arrays, what exactly is it meant by "globals"?

Variables in module-scope?
Static variables?

Does it also affect AAs in structs? For example:

struct S
{
    static int[int] x = [4:4];
}

Will this now work?

Yes, there are a few kinks that need ironing out though, hopefully before the RC in a couple weeks.

One open PR

Great work!

I'm just wondering about the -nothrow switch name:

"Adding the -nothrow switch to the compiler causes the stack unwinders to not be added and enables the optimizations. This capability is already there for -betterC code, this would just enable it for regular D code."

Why is it named nothrow if what it's really doing is not adding the unwinders?
A nothrow switch could imply it's doing something in relationship to nothrow, which it doesn't (unless it's secretly enforcing nothrow in the codebase).

-nothrow is equivalent to putting nothrow: at the top of every compiled module.

Ok, then it makes sense. Thanks!

That kind of goes against what it says in the changelog:

And it also mentions:

But surely it has effect on semantics? I assume scope statements are disallowed if -nothrow is set and would lead to compilation errors?

Static AA init, finally! Great!

Recursively adding nothrow: was implied but I err towards brevity.

Right, statements that depend on exceptions as part of their operation can't possibly work because no unwind tables, eh regions, etc... are generated.
