Do you really? Do the `functions` you use even fit the above definition?
I bet you can think of infinite number of functions (bool -> bool). The above definition admits only 4 such functions.
- bb010g 5y agoThere are only 4 (2**2) such pure functions. For type (Bool -> IO Bool), there are infinite (∞**2) such pure functions.
