Transform an IO action into a similar IO action that performs the original action only once.

You can choose to perform the original action in one of two ways:

  1. lazily (might never be performed)

  2. eagerly (concurrently performed)

Special thanks to shachaf and headprogrammingczar from #haskell irc for helping me reason about the behavior of this library.
