> Janet's purported focus is that it's easy to embed in a larger C program. There is Guile https://www.gnu.org/software/guile/ that is an implementation of Schema with the focus on being an extension language that integrates with C and C++. Wouldn't it more practical to adopt and contribute to it, rather than invent an own wheel?

Author here. Firstly, this is a rather silly argument in general. One could say that Embeddable Common Lisp and Guile address the same niche and all developers from one project should consolidate in the other. I have not used Guile to any extent, nor was Janet really influenced by it, but the comparison has been brought to my attention several times in the past. Janet is not scheme nor common lisp, so there are of co…

Names starting with a ‘j’ should be reserved for languages targeting JVM.

In the fine tradition of Jcala, Jotlin, Jroovy and Jlojure.

This looks so awesome! It's got the best parts of a lot of languages. This is what sticks out to me: - Really simple lisp like scheme, but reminds me of lua (and not bloated like CL) - Has resumable fibers, no callcc like scheme - Not missing the lack of lists tbh - A module system that doesn't feel awkward like CL - A built-in package manager (unlike CL) - Good lua and C support - Threads have a shared-nothing appro…

I never thought I'd see a Lisp without lists. Oh wait, I didn't because this isn't a Lisp. I know naming is hard, but this is getting out of hand. Don't say you're a Lisp when you're clearly not. Say Lisp-inspired. Don't use the term 'modern Lisp', 9/10 it's signaling the wrong thing.

Why was this downvoted? I don't get it :/

I don't use lisp languages, but one basic difference this has from other lisps is that functions accept multiple expressions, e.g.: (defn greet [firstname lastname] (def fullname (string firstname " " lastname)) (string "Hello, " fullname)) In other lisps, you'd have the last expression nested inside a `let` block: (defn greet [firstname lastname] (let [fullname (string firstname " " lastname)] (string "Hello, " full…

    (defun greet (firstname lastname &aux fullname)
      (setf fullname (format nil "~a ~a" firstname lastname))
      (format nil "Hello, ~a" fullname))
