OK, fair enough.

I've updated the enhancement request's title according to my previous comment.

Test:

-----------------------------------------------------------------------------

import std.conv;

void test1(T)(T lp)
{
    test2!( string)(lp);
    test2!(wstring)(lp);
    test2!(dstring)(lp);
    test2!(  char*)(lp);
    test2!( wchar*)(lp);
    test2!( dchar*)(lp);
}

void test2(D, S)(S lp)
{
    D dest = to!D(lp);
    assert(to!string(dest) == "Hello, world!");
}

unittest
{
    test1("Hello, world!" );
    test1("Hello, world!"w);
    test1("Hello, world!"d);
    test1("Hello, world!" .ptr);
    test1("Hello, world!"w.ptr);
    test1("Hello, world!"d.ptr);
}
