Why does all these pass:
     static assert(is(ElementEncodingType!(char[]) == char));
     static assert(is(ElementEncodingType!(wstring) == 
immutable(wchar)));
     static assert(is(ElementEncodingType!(byte[]) == byte));
     static assert(is(ElementEncodingType!(ubyte[]) == ubyte));

     auto range = iota(0, 10);
     static assert(is(ElementEncodingType!(typeof(range)) == int));
     static assert(is(ElementEncodingType!(immutable(ubyte)[]) == 
immutable(ubyte)));

But not this:
     static assert(is(ElementEncodingType!(AsciiChar[]) == 
AsciiChar));

omg forgot to import std.range 🙄

But the question is kinda still valid, like in the case of 
std.array.appender.

The original poster:
"Appender defines its element type with ElementEncodingType which 
only passes immutability through for built-in string types"
