Functional programming in small pieces

I've been articles on reading functional programming for some time, and little by little, I think I get a bit more of the whole stuff.

I found some nice articles/tutorials, and I understood most of them (yay!)

• Basic practical examples of ADT
• What's functional programming (surfacing side effects)
• Railway oriented programming
• Functional programming design patterns (great talk)

Although I'm still fighting with some other articles like this functional pearl about using foldr to make a function to give combinations of elements. It's been too long since I started looking at it, and I still don't get it.... :/

Well, have fun, and happy hacking.
