(That's the "world view on Haskell" issue I mean. I know this feeling
with physics: "what the heck are they talking about, this is just
mathematically wrong, ill-defined or otherwise void of contents?")

In Clean, print has the type
print :: (Int -> Int) -> Dynamic
but there is (hopefully) no equality on Dynamic . But it can be stored
in a file or something
store :: Dynamic -> IO ()
and loaded back. Thanks to IO, we can think of the file contents to be a
non-deterministically chosen intentional representation for a value with
I don't know whether Clean really does store that way, it may do more
and hence break the extensional semantics "a bit".
