It's in my copy of S06, which I haven't checked in yet. By the way,
the form is intended to work in either signatures or as an rvalue,
and in signatures replaces + to mark named args. + becomes the marker
for required attributes (assumed on initial positional args).

The absence of a dot creates a private attribute. We decided it should
be even easier to declare a private attribute than a public one, so it's
just
has $foo;
and then it is visible only in the lexical scope.
