Sorry if I am writing something silly, it's been a while ago I programed in D,
it seems I skipped the whole inout thing.

Feel free to modify/delete my comment or create new issue as you see fit.

Isn't there a similar problem with Unsigned(T)? Something like

unittest
{
    alias Unsigned!(inout(int)) U4;
    static assert(is(U4 == inout(uint)));
}


What I get with Unqual (with the original writln issue) is that there is a
problem with Unqual!(Unsigned!T), while Unqual!(T) does compile.

In code:

module main;

import std.traits;

int main(string[] argv)
{
    const int x = 1;
    //TestCallGood(x);
    TestCallBad(x);
    return 0;
}

/*public void TestCallGood(int value)
{
    Foo(value);
}*/

public void TestCallBad(inout int value)
{
    Foo(value);
}

public void Foo(T)(T value)
{
    Unsigned!T z;    //Unsigned!(inout(int)) is used as a type

    Unqual!(Unsigned!T) vBad = value;    //template instance
Unqual!(__T4ImplTNgiZ) does not match template declaration Unqual(T)
    Unqual!(T) vGood = value;
}
