Comment (by goldfire):

 Very interesting. What happens if you make a version of `FV` that uses its
 same setup (passing around partially applied functions, etc.) but without
 the list? Then rewrite the functions in terms of that?

 Also, I think it would be helpful not to use ticky profiling when
 generating these results (unless the data somehow comes from the ticky
 output), but also to include the allocations.

 Thanks!
