Do I have this right? "Remembering" Memoization!
For some applications, a lot of state does not to be saved, since "initialization" functions can be called early, and these functions will "remember" - (memoize) their results when called again, because of lazy evaluation?
You don't get memoisation for free. If you define a variable once in a where block, it's true that you'll evaluate it at most once, but if you repeatedly call a function "foo" that then calls "bar 12" each time, "bar 12" will be evaluated once per "foo" call. Cheers Mark
