Correction:

unittest {
    import std.stdio: wln = writeln;
    import std.string;
    alias z = toStringz;
    wln(typeof("a".z).stringof);
}

gives same error

t_string.d(7,19): Error: no property 'z' for type 'string'

Does anybody know if there is an Issue for this?

That's because you made the alias local, UFCS only works with global symbols right now (which is actually by design, though I don't think it is a great design). So this works:

// move these out to module scope
    import std.string;
    alias z = toStringz;

unittest {
    import std.stdio: wln = writeln;
    wln(typeof("a".z).stringof); // now we're good/
}

Ok. Great.

Still...I believe a warning hint should be outputted. This is not obvious.

Actually you're running into UFCS not working for module-scoped imports. The following will work:

-----
import std.stdio: wln = writeln;
import std.string;
alias toStringz z;

void main()
{
    wln(typeof("a".z).stringof);  // works ok
}
-----

UFCS not working for module-scoped imports is a filed bug.

Ok.

Great!

Please bugzilla, thanks! -- Andrei

Do you a reference to this bugzilla issue?

What were the motivations behind this choice of design?
