Guys, I was J-esting!

The URL I gave ( http://en.wikipedia.org/wiki/Tacit_programming )
is indeed a nice mini-intro to the ideas.
(see also http://www.haskell.org/haskellwiki/Pointfree ).

No one suggested deleting anything.

The 'code' section of our seqs is IMHO not a primary place of concern. 
I rarely find code that is incorrect (beyond repair).
(There are places where code is IMHO bordering on obfuscation).
The lack of code (and sometimes even definition) in some
(types of) seqs is worse.

There are other issues which I find more important,
like unreflected use (1) or random invention of (2) terminology:

Example for (1) (calling a million linear recursive seqs
"Generalized Fibonacci Numbers"):

Example for (2) ("amazing polynomial"):
