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

Simpler test case: import std.array: array; void main() { const(int)[] A = [1, 2]; array(A); } DMD 2.058head: ...\dmd2\src\phobos\std\array.d(55): Error: result[i] isn't mutable test.d(4): Error: template instance std.array.array!(const(int)[]) error instantiating 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.

Both cases fixed in 2.060.
