Bug 13763 – std.string.representation of immutables

I am not sure this is a bug, but it seems an incongruence: void main() { import std.string: representation; enum Enum : char { A = 'a' } const Enum[] a1; auto r1 = a1.representation; // OK immutable Enum[] a2; auto r2 = a2.representation; // Error } dmd 2.067alpha gives: ...\dmd2\src\phobos\std\string.d(1769,12): Error: cast from immutable(Enum)[] to immutable(ubyte)[] not allowed in safe code temp.d(7,17): Error: template instance std.string.representation!(immutable(Enum)) error instantiating

As in DMD v2.082.1, this compiles and executes as expected. Example code: void main() { import std.string: representation; import std.stdio; enum Enum : char { A = 'a', B='b', C='c'} const Enum[] a1 = [Enum.A, Enum.B]; writeln(a1.representation); // [97, 98] immutable Enum[] a2 = [Enum.A, Enum.C]; writeln(a2.representation); // [97, 99] } I am unsure as to whether this was "accidentally" fixed as part of the regular evolution of Phobos or was reported in a duplicate issue in fixed as a response to such. Either way, that's one issue less.
