Could someone explain to me (or point me to a reference explaining) the
purpose of the "some" and "many" methods of the Alternative class?
Also, there is a link posted in the documentation for
Control.Applicative to a paper which describes the motivation behind the
Applicative class; is there similarly a paper explaining the motivation
behind the Alternative class? (The problem with Googling for
"Alternative" is that this word is used a whole lot of the time, and
very rarely does it refer to the Alernative class. :-) )
