[Haskell-cafe] Is Haskell a Keynesian language?

Here is another approach of questionable classification of languages. :-) A lazy functional program is demand driven, an imperative program is supply driven. That is, if I request some information by calling a function in GHCi or Hugs, the interpreter develops a plan a how to produce the information I need and then executes the necessary steps. In contrast to that, an imperative program executes what's next on the schedule, whether it is need or not. So is Haskell a Keynesian language and C++ a Say language?
