A "thunk" is, in general, a piece of code which represents a
suspended or delayed action. In Haskell, it represents a lazy
computation: Haskell will only evaluate the code if the value is
actually needed, and even then only just enough to satisfy the
immediate need (thus, the result of evaluating a thunk may be a
value, or another thunk).
