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

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++.
In C++ I would expect the copy to be optimized away, even when
passed by value. Do you mean d-compilers (optionally?) do the
same optimization too?
