Hi Stefan,
in the Teletype module, it would probably be better to reflect
IOTeletype operations as:
data Action a = Finish a | Put Char (Action a) | Get (Char ->
Action a)
That way, there is no need to use (unobservable) laziness.
I'm afraid I've lost you. How does this differ from the current
definition of IOTeletype?
Thanks,
Wouter
