Take this bit of code
import std.stdio;
import std.traits;
void main()
{
writeln(Unqual!(char[]).stringof);
writeln(Unqual!(wchar[]).stringof);
writeln(Unqual!(dchar[]).stringof);
writeln(Unqual!(const char[]).stringof);
writeln(Unqual!(const wchar[]).stringof);
writeln(Unqual!(const dchar[]).stringof);
writeln(Unqual!string.stringof);
writeln(Unqual!wstring.stringof);
writeln(Unqual!dstring.stringof);
writeln();
writeln(Unqual!(ubyte[]).stringof);
writeln(Unqual!(short[]).stringof);
writeln(Unqual!(uint[]).stringof);
writeln(Unqual!(const ubyte[]).stringof);
writeln(Unqual!(const short[]).stringof);
writeln(Unqual!(const uint[]).stringof);
writeln(Unqual!(immutable ubyte[]).stringof);
writeln(Unqual!(immutable short[]).stringof);
writeln(Unqual!(immutable uint[]).stringof);
}
It prints out
char[]
wchar[]
dchar[]
const(char)[]
const(wchar)[]
const(dchar)[]
string
immutable(wchar)[]
immutable(dchar)[]
ubyte[]
short[]
uint[]
const(ubyte)[]
const(short)[]
const(uint)[]
immutable(ubyte)[]
immutable(short)[]
immutable(uint)[]
None of those const or immutables should be there. The only changes between
this and not using Unqual at all is the const T[] are now const(T)[] and the
immutable T[] are now immutable(T)[]. And the immutable(T)[], are still
immutable(T)[]. The immutable on their elements aren't stripped.
Unqual specifically states that it removes _all_ qualifiers. It's clearly only
removing them from the array itself and not the elements, so it's not removing
all of the qualifiers.
