Bug 11422 – std.array.assocArray with const tuple values

I think both cases need to be accepted or both need to be refused: import std.array: assocArray; import std.range: zip; import std.typecons: Tuple; void main() { auto keys = [10, 20, 30]; const vals1 = [1, 2, 3]; //keys.zip(vals1).assocArray; // OK alias R = Tuple!int; const vals2 = [R(1), R(2), R(3)]; keys.zip(vals2).assocArray; // Error } dmd 2.064beta4 gives: ...\dmd2\src\phobos\std\array.d(249): Error: template std.typecons.Tuple!int.Tuple.opAssign does not match any function template declaration. Candidates are: ...\dmd2\src\phobos\std\typecons.d(504): std.typecons.Tuple!int.Tuple.opAssign(R)(auto ref R rhs) if (areCompatibleTuples!(typeof(this), R, "=")) ...\dmd2\src\phobos\std\array.d(249): Error: template std.typecons.Tuple!int.Tuple.opAssign(R)(auto ref R rhs) if (areCompatibleTuples!(typeof(this), R, "=")) cannot deduce template function from argument types !()(const(Tuple!int)) const test.d(10): Error: template instance std.array.assocArray!(Zip!(int[], const(Tuple!int)[])) error instantiating

On git HEAD I get "Error: static assert "assocArray: value type must be mutable"", so this seems to have been fixed. Closing.
