I think really there's not much distance between us. I certainly wouldn't
want to destroy the facility for in-line pipes in commands, for those
who have it. I don't see any use in throwing away a simple mechanism
that makes sense for a lot of purposes, just for the sake of a clumsier
one that is SOMETIMES useful! I, also, don't see why we can't have both,
especially if the added facilities are through a PIPE command external
to any shell.

Sorry -- I wasn't trying to argue against that. It just seemed
that your experience with those programs was contrary to mine.

For sure! I just thought you meant a total failure!
And, as to my further comments...

Yes. I apologise for somewhat hasty conclusions.
