Surely the name suggests that "interactive" behaviour is required, i.e.
exactly some interleaving of input and output. The chunk-size of the
interleaving should depend only on the strictness of the argument to
"interact".
I'm not happy that interleaving depends on the strictness. Lazy or strict evaluation should only change the behaviour of overall termination (lazy evaluation should terminate more often). I'ld rather implement interleaving (or "interactive" behaviour) explicitely by:
interact f = do s <- getLine putStrLn (f s) interact f
(assuming line buffering) (Terminating with "ctrl-c")
Surely also something is needed for endless character resources as Tom pointed out.
