[Haskell-cafe] Object Oriented programming for Functional Programmers

[MigMit]

Well, "functional programmer" is a relatively broad term. If you're coming from academia, so that for you Haskell is some sort of lambda-calculus, spoiled by practical aspects, then I'd suggest Luca Cardelli's book "Theory of Objects".

Also, as Daniel told you already, don't start from C++, it really has very little to do with OOP. It's primary merit is a very powerful system of macros (called "templates" in C++ world), not objects. If you want something mainstream, Java would be a good choice, and C# even better one (although it would be more convenient for you if you use Windows).

Or you can try OCaml, which is functional enough for you not to feel lost, and object-oriented as well.

Eventually, I had to program in Pascal and Prolog for my University (where I learned Haskell). I also did some PHP, SQL and HTML while building some web sites, languages that I taught to myself. I have never had any contact with JavaScript though.

Haskell was the first programming language I learned, and subsequent languages never seemed so natural and worthwhile to me. In fact, every time I had to use another language, I created a combinator library in Haskell to write it (this was the reason that brought me to start with the HaTeX library). Of course, this practice wasn't always the best approach.

Haskellers are frequently comparing Object-Oriented languages with Haskell itself, but I have never programmed in any OO-language! (perhaps this is an uncommon case) I thought it could be good to me (as a programmer) to learn C/C++. Many interesting courses (most of them) use these languages and I feel like limited for being a Haskell programmer. It looks like I have to learn imperative programming (with side effects all over around) in some point of my programming life.
