Will methods explained here work for boolean expressions?
The convenience of defining using specialised datatypes for serialising numeric operations comes from Num being a typeclass. This is not the case for Bool: Prelude> :info Num class (Eq a, Show a) => Num a where (+) :: a -> a -> a ... -- Defined in GHC.Num Prelude> :info Bool data Bool = False | True -- Defined in GHC.Bool
Is there a way to extract parameter names from function definition to use them in Show instance? Or should I just use same names everywhere?
The only kind of introspection I know comes from Template Haskell, but
I'm sure there are other methods that I'm not aware of available.

Many thanks for your help! Seems to be what I need. Two more related questions:

In case that helps, here's the code I need to convert (the code in where part of solveScheme): http://npaste.de/aKY3cn0xZf/
