You can't do that. New strings are created frequently by concatenation, they're best thought of as units - like int. They need to handle their own allocation, there's no two ways about it.

Autodecoding hurts "half" of the users - those who don't need it for the task. De-encapsulating string as an unstructured slice hurts the other "half" - those who need things like Unicode semantics, simple string manipulation, and good use of memory.

The view that strings must be char[] and that that's the "simple" choice has been a disaster for D. (I believe I have started to convince Walter of that.) It's simple like Go is simple - forcing complexity realities on users. Incomparably larger than autodecoding. It has forced virtually all string-processing code in D to use the garbage collector. Immutable was a short of adrenaline that prolonged the lifetime of strings by ten years. Before that, having unstructured strings that were also weirdly mutable was a double disaster.

We must have a UTF8 reference counted string that assists built-in literals of type immutable(char)[] and rally the entire language ecosystem around those.

I appreciate the gesture Andrei, and have the utmost respect for people who are willing to apologize.

DirEntry is implicitly convertible to string because it needs to be usable with std.file, which is a big untyped ball of strings.

Well, you see, strings have the disadvantage of being constructs that represent exactly the wrong abstraction: they're a slice of chars, period.

To see the problem with this, consider:

writefln(
  "äöü are %s letters; the second one is %s",
  "äöü".length,
  cast(ubyte[]) "äöü"[1..2]);
