Heh. I still remember in my first Comp Sci class, in C, I had to take a 2-line recursive tree traversal...and write it iteratively (in like 50 lines).

OK, if we old lags are going to give our excuses... I was a member of an undergraduate society in Cambridge called the Processor Group. I went along to a talk that Arthur Norman gave to them (must have been 1980±1?) in which he described (S, K, I) combinators and his plans for the SKI Machine (SKIM). The fact that S and K on their own gave a complete computational basis was the most exciting piece of computer science I'd encountered at that point and I just had to follow it up. So some years later I ended up at that same 1987 meeting. -- Jón Fairbairn [EMAIL PROTECTED] ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Re: How did you stumble on Haskell?
I started using Python around 1998, and I loved the elegance of it, but I was frustrated with the performance. Around 2001 I was poking around for something that would give me better performance but still allow some nice capabilities for abstraction. I started using OCaml after reading a commentary from one of the Shootout guys that he had been impressed with it. I loved the performance and the parametrized modules, but the lack of overloading was frustrating. Once I was looking for a nice rule of thumb for when to use foldl vs. foldr, and was disappointed to hear "Just use foldl - it's tail recursive." Maybe there's a place for folding right in a strict language, but I haven't seen it. Once I was deep into OCaml, Haskell kept coming up, since so many people using OCaml also like Haskell. Seeing some elegance in "A Gentle Introduction to Haskell" and not immediately understanding it got me hooked right away. And there's a time to fold right!

Awhile back, I decided that, once I got familiar and comfortable with a programming language, I would learn a new one. I tend a learn a new language every 1-3 years on average. I had been a convert from Perl to Python a few years back. I got comfortable with Python and decided I want to learn a new language. I looked at a number of them. Rejected Ruby because it was too much like Python, Erlang because it didn't seem general-purpose enough, Haskell because its library seemed small at the time and the focus too academic. I eventually learned OCaml. OCaml was an interesting experience. It had some nice features. But I/O was absolutely infruriating. OCaml's default I/O system can't handle files opened read-write, for instance. It also has two distinct list-like types: one that's lazy, one that's not, and they require two distinct sets of functions to work with. The object system also is complicated. The syntax and whole idea of .ml vs. .mli file felt very dated and the build system was extremely difficult to get right. So I again searched out a language, with largely the same results for everything except Haskell. I can't remember exactly what changed my mind about Haskell. It may have been Cabal, it may have been Darcs, or something else. In any case, I decided to pick it up. I was pleasantly surprised that Haskell seemed to have all the things I liked from both Python and OCaml and none of the annoying things from either. It's been a fun experience. Haskell is the only language I've ever learned in which I have used it for something like 2 years, written numerous applications, developed several libraries, even written links to C and Python, and still consider myself a newbie. And that is a GOOD thing. -- John ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
