Friedman's books are all great. All of them. But they don't work for everybody. If you can be relaxed and think of the interaction as play, they're very good. If you're feeling more of a "serious business" mindset, it can be hard to get in the groove of his style. There are a lot of jokes about food and encouragement to take breaks. If you can get into the learning as play mindset, I'd strongly encourage taking... - Source: Hacker News / 7 months ago

- pipe operator It compiles to either erlang or JavaScript, so I was able to jump right into building something fun with a new language. >I previously gave Clojure a try, that was a pretty good fit, but the JVM / ecosystem put me off. I felt similarly w/ leiningen (too much boilerplate) but was lisp-curious still so gave racket (https://racket-lang.org/) a try and appreciated the batteries included philosophy of... - Source: Hacker News / 8 months ago

Biased recommendation: Try racket https://racket-lang.org/ It's not pure functional, but the preferred style is to use mostly functional constructs. (But you can cheat when it get's too difficult or you need some extra speed.) (And you can download packages like Qi that enable a new language inside Racket that has more support for functional style.) (Most Schemes have a similar mostly-functional style, so you can... - Source: Hacker News / 9 months ago

For Scheme implementations there are LIPS and biwascheme. I haven't done more than play around with them, so I can't really give an informed opinion about pros and cons or favorites. Source: almost 2 years ago

In my interpreter, LIPS Scheme, vector literal syntax is created using a syntax extension, a token that is mapped to a function or a macro. So you can use things like this:. Source: about 2 years ago

I'm not sure about other Scheme interpreters but in my interpreter LIPS Scheme, there is (env) function that returns a list of symbols. You can also access environment objects e.g. (current-environment) return object that is used internally. And you can even access the scope chain because the env object has __parent__ property that returns the parent scope. Source: over 2 years ago
