I'm reading some d-sources, and it looks like they pass big structs by value.

Such as:

    Matrix4x4f opBinary(string op)(Matrix4x4f rhs) { ... }

I came from a C++ background, and I would have written:

Matrix4x4f opBinary(string op)(const ref Matrix4x4f rhs) { ... }

I haven't found anything in the docs yet. Will the d-compiler optimize them into virtually the same? Can someone give me a reference?

It's the same as C++.
