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.
