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`.
in is synonymous for "const scope".
Doing "const scope ref" yields:
"scope cannot be ref or out"
which makes sense. Just use const instead.
