How did you “flip the switch” in your brain to the functional mindset?


      

      
What I found important is the following:
- to make your functions declaritive, then you can improve on them later
- do what Geraint Jones has called "wholemeal programming"; it helps
prevent a disease called "indexitis" and encourages lawful program
construction (from "Pearls of Functional Algorithm Design", Richard
Bird, 2010)


    

    

    "Functional languages excel at wholemeal programming, a term

    coined by Geraint Jones. Wholemeal programming means to think

    big: work with an entire list, rather than a sequence of elements;
    develop

    a solution space, rather than an individual solution; imagine

    a graph, rather than a single path. The wholemeal approach often

    offers new insights or provides new perspectives on a given problem.

    It is nicely complemented by the idea of projective programming:

    first solve a more general problem, then extract the interesting

    bits and pieces by transforming the general program into more

    specialised ones."
