... and miss the point completely.

You remind me of people who criticize where I go on vacation and what I do. "You could have gone to xxx and done yyy." Yeh, well, no matter where I go and what I do, I could have gone somewhere else and done something else.

Time and resources are limited. Some people would rather get on with the doing rather than learn new ways to not do things they don't have time for because they spend all their time learning new ways they won't use.

Yeah, you're right. We should never try anything new or do anything differently from how it's
always been done.

You just don't get it. There are more people who already know common languages than who already know OCaml, and only a fraction of those people who don't know OCaml are going to have the time and resources to learn it.

It's just a simple fact. It has nothing to do with the benefits of education, of new and improved ways of doing things. NOTHING.

Quit taking it personally. It has zero to do with you personally, your personal taste in languages or living styles, what would be best or ideal or anything. It is a simple fact of counting heads. More people know languages other than OCaml and could contribute in those languages.

Separate raw data from your personal wishes and dreams. Valerie wrote a fact. Dispute the fact if you want, but don't ramble on about learning and better ways and so on, those are not facts.

Looks to me like you're putting words in rwmj's mouth and then disagreeing with them. I don't see that rwmj has taken issue with Valerie's conclusions about the language choice.

Not every comment is a contradiction of the parent, and I wouldn't assume that "learn something new" was meant to say, "there's nothing unfortunate about the fact that this code is in OCaml."

Of course, I'm not really sure how "learn something new" does fit into the thread. The posts after it follow more obviously: you point out that learning something new isn't always the right thing and rwmj misreads that as learning something new is never the right thing and disagrees. While that position (learning something new is sometimes good) is obviously right, you respond as if he were arguing -- still -- that there's nothing unfortunate about the fact that this code is in OCaml.

I was just being sarcastic in that second posting. OCaml and Haskell are something new. They're not just exotic scripting languages - in the way that Ruby is just Perl with a different syntax. They are something considerably more powerful and expressive that can take programming in new directions. Unfortunately explaining this is a bit like the Paul Graham explaining LISP to "Blub" programmers.

It's hard to find explanations that do a worse job of introducing people to Lisp. There's a good explanation of Haskell (PDF), including a bit of history, design choices and an overview of the functional programming paradigm.

Haskell, by the way, is roughly of the same age as Python, but is expected to become the next great programming language Any Moment Now. Or maybe not.

No-one's saying that people *shouldn't* learn OCaml, or even that they personally don't wish to learn OCaml, just that in practice most of the people in the programming world perceive OCaml as exotic and do not learn it -- for whatever reason.

Writing in a niche language *can* have the opposite effect on finding contributors, though. Darcs for instance benefited quite a bit from being written in Haskell, because there were many people who had learned the language out of interest and really wanted to work on something in Haskell, but not many real-world projects to go around. Its competitors were written in better known languages, but their potential contributor base was correspondingly diluted by all the other projects also written in those languages...

This effect does exist but it's short-lived...

Yes, darcs benefited for a time from the fact that it could attract all these people - but the end result was the same: when C crowd got it's shiny new bauble (Git) all other projects were left in dust...

Sometimes it's good idea to use non-mainstream language because it's the only way to produce something and you don't need many contributors: one of the most popular DFT library (FFTW) is written in OCaml (well, kinda). But it does limit number of potential contributors! No way to avoid this...
