Idiom #37 Currying

Technique of transforming a function that takes multiple arguments and returning a function for which some of the arguments are preset.

Code 
(curry range 1)
Code 
(curry range 1)
Comments bubble
range(a,b) = [a..b]
(curry range 1) = _λ i ↦ [1..i]
Comments bubble
range(a,b) = [a..b]
(curry range 1) = _λ i ↦ [1..i]

Haskell begins with most functions already curried and allowing partial projection, hence the uncurried range sprang to mind as a notable exception for this illustration.
