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);
}


DMD 2.058 Head:

...\dmd2\src\phobos\std\array.d(55): Error: result[i] isn't mutable
test.d(5): Error: template instance std.array.array!(Result) error
instantiating
