Have you even considered the space costs of this? For almost any non-trivial bit of code I've written, automatic memoization would result in a completely useless binary, as it almost guarantees horrific space leaks.

And a compile-time option, where the programmer explain which functions should be memoized? ghc -fmemoize=foo,bar darcs.hs
