I don't follow the connection to Lisp-2. Can you explain?
There isn't one, I fatfingered my 1 into a 2 and it's too late to fix it, sorry. I just meant it ends up being the shortest, least weird notation for function composition. Clearly, the meta-notation has some problems...
It seems like an example of the importance and influence of notation - many commonly used languages these days have first class functions but nobody using a lisp-2 variant would have thought to give this particular thing a special name.
