I'm guessing the intent on enabling this enhancement left with Kenji Hara, and
reminders about it left with bearophile?

Other basic cases that can be supported:

void main() @nogc {
int[2] a = [10, 20];
int[3] b = [40, 50, 60];
int[6] c = a ~ 30 ~ b;
}


Currently DMD 2.066alpha gives:

test.d(4,16): Error: cannot use operator ~ in @nogc function main
test.d(4,16): Error: cannot use operator ~ in @nogc function main
