Probably not very good idea from me, I understand that I was wrong thinking!

In case you really-really-really want it, such behavior can be achieved via std.typecons.Tuple :

import std.typecons;

auto foo()
{
    return tuple(true, "text");
}

void main()
{
    auto ret_val = foo();
    assert(ret_val[1] == "text");
}

Luckily, there is no global namespace in D. So, when it makes sense module-level global variables are fine as well.
