Why does std.container.array use refcounted? Seems like serious overhead compared to std::vector in C++.

Because std.container have reference semantics.

Apologies, wrote this inbetween classes and didn't bother to check array's implementation. I thought it was implying each item was individually wrapped by a refcounted i.e, not in a continuous block of memory and was confused.
