Bug 20502 – Converting std.typecons.RefCounted!T to a string gives T's storage location instead of T's fields when T is a struct without an explicit toString

Converting std.typecons.RefCounted!T to a string gives T's storage location instead of T's fields when T is a struct without an explicit toString. Demonstration: --- void main() { import std.typecons : refCounted; import std.stdio : writeln; writeln(123); // "123" writeln(refCounted(123)); // "123" struct A { string toString() { return "a"; } } writeln(A.init); // "a" writeln(refCounted(A.init)); // "a" // This one doesn't match: struct B { int x; } writeln(B(123)); // "B(123)" writeln(refCounted(B(123))); // "RefCounted!(B, cast(RefCountedAutoInitialize)0)(RefCountedStore(558C7FFBC660))" } ---
