Things I figured out about Haskell today

[maradydd]

• Maybe is the same thing as Kleene ? (the "zero or one" operator in regular expressions).
• A typeclass is the same thing as an STL concept, but a typeclass actually means it.
• instance means "We're going to make this data type an instance of this typeclass, and here's how."

Now if I can just get my head around monads, I'm set.

Almost exactly a week. I learned Common Lisp back in grad school, and I tend to write Python and (god help me) C++ in a fairly functional style, so I'm in the same boat as you. I'd been wanting to pick up Haskell for a while, and a friend and I decided to collaborate on a project in it. He's more experienced at it than I am, so he's been a very helpful guide.
