[pipe] as default stores and delays float numbers. If you bang a
[pipe] object it will kind of see it as if you'd send a 0. Funny
things will happen if you send something different. 

You can make a pipe expect symbols by using it as [pipe s 0].  You
also can make pipe expect pointers, but unfortunatly you cannot make
it expect variable length lists AFAIK.

See attached example patch.
