A D2 program:
import std.algorithm: map;
import std.array: array;
void main() {
auto r = map!q{ "A"[0] }([0, 1, 2]);
auto a = array(r); // Error: result[i] isn't mutable
assert(a == "AAA");
}
DMD 2.052 gives the errors:
...\dmd\src\phobos\std\array.d(62): Error: result[i] isn't mutable
test.d(5): Error: template instance std.array.array!(Map!(result,int[])) error instantiating
In my opinion array() needs to be able to build an array of immutable items too, like a string from its immutable chars.

Issue does not occur for me on head revision, DMD v2.064.

OK, closed, despite I don't know if the test suite has a test case like that.
