Nice to have: initialization of static arrays of builtin types

[schveiguy]

C:

int x[10] = {0};

D:

int[10] x = [0];

Results in a compiler error for size mismatch. Nicer would be:

int[10] x = 0;

This won't work in all situations, but the current behavior will never work.

Only in function scope apparently:

void main()
{
	int[10] x = [0]; // error
}

int[10] x = [0]; // no error?

Kinda surprised.

But indeed, initializer translation needs work. In C, {0} can initialize almost anything. D is a lot more specific and picky with initializers.

Huh, that's odd.

But I was actually thinking -- would it be possible to write an allZeros!T template that properly initializes any type? That could be used in its place. It might not be easy to do with CTFE.

Normally when translating, I have just been removing the initializer and using auto initialization. The one place where it is a problem is floating point types or char buffers.

Fixed by recognizing {} and {0} on static arrays in 0f31729

I'm thinking that char/float members of structs should add a = 0; on the D side so S.init can be used.
