D offers more low-level knowlege/control here, it doesn't
decide to pass by value or reference, leaving the decision to
the programmer, I prefer D here.
But in D code like this, where a large value is passed, I'd
like the D compiler to give a warning (despite once in a while
that's exactly what you want?):
alias int[1_000] TA;
void int(TA a) {}
I was surprised a little when compiler rejected `ref in`.
