First, I am using DMD 2.039, for which there is no entry on the "Version"
field. Anyway, I firstly bumped into this when using DMD 2.037.

So, when compiling this code:

import std.variant;

void main()
{
   bool[int] a;
   auto x = a.keys[0];
}

The compiler crashes saying:

        deferring sigaction_t
dmd: mtype.c:3882: StructDeclaration* TypeAArray::getImpl(): Assertion `impl'
failed.

---

Removing the 'import std.variant;' statement solves the problem.

Replacing the 'bool[int]' with 'int[int]' (and still importing std.variant)
makes the compiler say:

        deferring sigaction_t

But it still generates the executable, which seems to work as expected (that
is, throwing a "Range Violation").
