Anonymous records. A solution to the problems of record-system.

#Anonymous records. A solution to the problems of record-system.

Please, beware that the proposal that follows has been implemented as a library.

The current record system is notorious for three major flaws:

  1. It does not solve the namespacing problem. I.e., you cannot have two records sharing field names in a single module. E.g., the following won't compile:

    

    2. 



data A = A { field :: String }

                Proof that fmap f . fmap g = fmap (f . g) given fmap id = id, and the free theorem for fmap's signature.
              
          

        

      

        

  

      

    
##Theorem:


Given fmap id = id:


fmap f . fmap g = fmap (f . g)


To prove this we're going to need a few lemmas:
