Editing Continuation (section)

==== Functional metaphors ====

* Continuations represent the future of a computation, as a function from an intermediate result to the final result ([http://www.haskell.org/haskellwiki/All_About_Monads#The_Continuation_monad] section in Jeff Newbern's All About Monads)
* The idea behind CPS is to pass around as a function argument what to do next ([http://users.umiacs.umd.edu/~hal/docs/daume02yaht.pdf Yet Another Haskell Tutorial] written by Hal Daume III, 4.6 Continuation Passing Style, pp 53-56. It can also be read in [http://en.wikibooks.org/wiki/Haskell/YAHT/Type_basics#Continuation_Passing_Style wikified format]).
* Rather than return the result of a function, pass one or more [[Higher order function | Higher Order Functions]] to determine what to do with the result. Yes, direct sum like things (or in generally, case analysis, managing cases, alternatives) can be implemented in CPS by passing ''more'' continuations.
