Odd. Does it happen with the module header

module Main where

, with an explicit export list, or without any module header?

Is it so that with the main function, you load the compiled function, then when you get 
the Not in scope, you remove the main function and reload the module without compiling?
Then it's probably the correct behaviour, cf. the user's guide, section 3.4.3. What's 
really in scope at the prompt?
