The type I would need for bind is this one:
 (>>=) :: NFData sa => LI sa -> (sa -> LI b) -> LI b
Will this do?
(>>=) :: (NFData sa, NFData b) => LI sa -> (sa -> LI b) -> LI b
No this one would be too strict. In particular functions are not member of
NFData (and for good reasons) and we may want to have LI values holding non
"forcable" values.

However I got your idea and it can be useful.

Thanks,
