The syntax looks clean, akin to Python, but with terser record types. This would make a nice config or an embedded language like Lua.

One thing I’d appreciate here is a “Why Rhombus?” page, even if the rationale is simply that it’s fun.

Edit: Turns out there’s a goals[1] page. Rhombus is trying to replace Lisp’s parenthesis-heavy syntax with something cleaner while keeping Racket’s powerful macro support.

This is racket's [rhombus], which might be an interesting second link here; it's a scheme, underneath, with the full power of Racket libs available.

[`shrubbery`], the replacement for s-exprs, is pretty interesting, expanding s-expr simply with grouping, and then a separate infix-pass on top. I've been playing with using it as the basis for a separate language; it's in an interesting place in the AST space, especially given the forethought put into macros.

From the 2nd example:

class Rect(left, top, right, bottom)

fun rect_like_to_rect(v): match v | Rect(_, _, _, _): v | {"LT": [l, t], "RB": [r, b]}: Rect(l, t, r, b) | {"TL": [t, l], "RB": [b, r]}: Rect(l, t, r, b)

rect_like_to_rect({"TL": [0, 2], "RB": [10, 5]}) // ⇒ Rect(0, 2, 10, 5)

Isn't this wrong? I'd expect to see Rect(2, 0, 5, 10) instead.

It also seems like "RB" was meant to be "BR".

Graaah, totally missed it. Thanks!

Thanks. It’s nice to see at least a few in the FP community recognize that Lisp dialects, with their parenthesis-ridden S-expressions, are hard to read and write.

I guess it's a typo and the second line should say "BR". I just send a PR to fix it.

This actually looks good. It's like a less-obtuse Haskell. At a glance the features seem to be just the right mix of functional programming paradigms and standard imperative programming.
