No, and it doesn't work for C++ either. Consider:

void foo(const ref S s)
{
assert(s.a == 3);
bar();
assert(s.a == 3); // OOPS!

Here's the bug you want to vote up:

It is indeed a sad situation.

I just noticed that when a method has a ref parameter for a struct, it doesn't
get inlined:
union Matrix4x4 {
struct { float _11, _12, ...}
float[4][4] m;
float[16] v;
Matrix4x4 opMul(const ref Matrix4x4 m) const { ... }
void opMulAssign(const ref Matrix4x4 m) { this = opMul(
