And that's fine for your code, but if you want D and DMD to be a system that people use for larger systems, then cutting down the sheer number of things that don't work when pushed is kinda important.

True, but I would never write code that tried to throw an exception across language boundaries, anyway. It's just asking for trouble.

It's more than just catching. That's a relatively minor issue. The bigger one is stack unwinding and related cleanups. Consider: c++ function with local variables that have dtors that calls a D function that throws. Those c++ locals will never have their dtors called. It's not a huge problem, but the sum of the problems add up to pain and will need to be fixed at some point. The lack of pain today is that it's barely feasible to mix languages where more than one has any exception handling right now. Something of a catch-22 of issues, imho.

What does that practically mean from the users point of view? It means D cannot throw or catch VC exceptions, and VC code cannot throw or catch D exceptions. Pretty much just like on Linux/OSX/FreeBSD, which doesn't seem to be a problem.

Interoperability isn't a single attribute. It's an accumulation of tons of attributes. Much like .so/.dll support. So, 2 steps forward, but 20 left (obviously making up those numbers).

A note on your Vector implementation. Currently you use the
vector operators, e.g.
Vector!(T,size) opAddAssign (Vector!(T,size) v)
body
{
arrayof[] += v.arrayof[];
return this;
}
This is fine for large vectors, but (correct me if I'm wrong),
your vector class appears to be designed for small vectors. Those
vector ops currently call a asm optimised function that uses SIMD
instructions in a loop - it works well for larger vectors with
hundreds of elements, but for small vectors it's significantly
faster to just use:
foreach (i; 0..size)
arrayof[i] += v.arrayof[i];
I've also noticed that you've provided Matrix2x2 and Matrix4x4 as
separate structs from the more generic Matrix. I'm guessing this
is for specialisation. A more idiomatic way to handle this would
be to use template specialisation to provide the optimised
versions. That way, when people use Matrix!(T, 2, 2) they get all
the benefits of Matrix2x2!T as well.
