show function question

[rui yang]

Hi,everyone

Suppose I have a function:

compFix :: (F1,F2)->(F1,F2) which have functions as it's arguments and returns 
functions as it's results,here two arguments have types for example:
type F1 = Int -> Bool
type F2 = Int ->[Int] 

How should I define the instance declaration of Show class for my function type 
variables so that I can print the list of argument-result pairs out?

Thanks

Rui
