Get rid of plumbing at the command line level.  It is confusing to
users, and command line arguments, exec calls and I/O streams are not
efficient and reasonably typed mechanisms for the kind of operations
done in plumbing.  Instead using a good extensible portable scripting
language (I consider Lua quite suitable in that regard, but it is
conceivable that something with a native list type supporting easy
sorts, merges and selections could be more efficient) and implementing
plumbing in that or in C would have been preferable for creating the
porcelain.

That would keep plumbing out of the hair of users and make it easier to
cobble together extensions and variations with non-trivial internal
dataflow.

Shell scripts have also proven to be a constant hassle with regard to
portability and bugs (like underquoting).
