The tcl::chan::halfpipe package provides a command creating one half of a tcl::chan::fifo2 pair. Writing into such a channel invokes a set of callbacks which then handle the data. This is similar to a channel handler, except having a much simpler API.

The internal TclOO class implementing the channel handler is a sub-class of the tcl::chan::events framework.
