I have one minor comment about join. You should specify its behavior

I think it makes the most sense for it to return an empty string,
which is a reasonable degenerate case of a string-join. -- Darren Duncan
join returns a string, and requires a list. undef would indicate an
exceptional condition (for example the list contained an object which
could not be stringified), so I don't see why a valid (but empty) list
would cause an undef to be returned. The later point about C<[~]()> is
also quite helpful. I've made a note in my copy of S29, which will be
committed to the pugs repo as soon as I have commit rights.
