Want to learn functionnal programming , just download GCL

check out a few Lisp tutorials on Youtube and you good to go. Dont try to apply fuctionnal principles to procedural languages , if you are a beginner.

Using Lisp will force you to do and understand functionnal programming. And frankly , Lisp is a lot of fun and easy to start with. Dont be afraid by all these nasty (()) and weird (+ 4 5) operations , it will make sense quite fast.

something like

    (defun add(a b)
        (+ a b)) 

    (add 4 5)

is actually easy to understand , isnt it ?
