Well, you can get "A Novel Representation of Lists and Its Application
to the Function 'Reverse'" by John Hughes online published in 1986
which is referenced by Wadler's 1987 "The Concatenate Vanishes" and
references Richard Bird's 1984 paper "Transformational programming and
the paragraph problem" though I'd be quite surprised if that was the
first place the representation appeared in print.

There's a long-known technique in functional languages where [x1,...,xn] => \tail -> x1:...xn:tail xs ++ ys => f . g xs => f []
A correspondent mentioned to me that he couldn't find a reference to the idea (which I gather he had independently rediscovered). I know I've read about it somewhere. Can anyone provide a reference?
