           Summary: std.array.array of mutable range of cost items

I think std.array.array shoult support code like this too, if possible:


import std.algorithm: map;
import std.array: array;
void main() {
    auto r = map!(a => cast(const int)a)([1, 2]);
    array(r);
}

test.d(5): Error: template instance std.array.array!(Result) error

Simpler test case:


import std.array: array;
void main() {
    const(int)[] A = [1, 2];
    array(A);
}

I have also renamed this bug report.

This is borderline between a bug and an enhancement request.

I suspect the reason std.array.array does not handle this case is due to an
oversight and is not part of the design, and this is therefore a bug.
