My enhancement request was for the array[$] syntax. The idea of []s was invented by someone else (Timothee Cour?).

I like the practical comments by Hara. If Kenji thinks the []s is not useful for efficiency (because the efficiency can be obtained with just improvements of the compiler), then the []s syntax becomes less necessary.


On the other hand this is an interesting use case that compiler improvements alone could not be enough to allow:

void fun(int[3]) {}
void main() {
    int[3] x = [1, 2, 3];
    fun(x); // OK
    fun([1, 2, 3]); // error
    fun([1, 2, 3]s); // OK
}


Are vector ops supported?

int[6] a;
a = [1,2,3]s[] + [4,5,6]s[];

DIP34 is still a draft, and it shows, some corner cases are missing in that document and need to be found, fleshed out and added to the DIP34.
