No, but you can't do:

     $string =3D (string) $datetime;

But can do:

    $string =3D (string) $ustring;

Where $ustring is instanceof UString.

Even if you never write $string =3D (string) $ustring, the engine will
perform the same
action all the time, whenever you pass a UString to anything expecting
string.

It feels like a complete implementation should support both casts.

Cheers
Joe
