Higher-order Functions - slide 24 : 34

It is possible to achieve 'the currying effect' by generalizing functions, which requires two or more parameters, to only require a single parameter

Motivation:

Expression	Value
(map li (list "one" "two" "three"))	("<li>one</li>" "<li>two</li>" "<li>three</li>")
(define li-mapper (map li))	map: expects at least 2 arguments, given 1
(define li-mapper ((curry2 map) li)) (li-mapper (list "one" "two" "three"))	("<li>one</li>" "<li>two</li>" "<li>three</li>")

The function curry-generalized.
