seems interesting

some unordered thoughts upon reading their guide (starting with "oh nice they have documentation")

setq? okay this is definitely more of a lisp than a scheme, huh
- yup, looks like a lisp-2. fair enough, i guess
…lists are vectors of elements? i wonder how they pull that off, given the semantic differences between vectors and linked lists. how do they represent non-list pairs?
- on further reading: that... could almost work. cdr making a slice is clever. doesn't address the dotted-pairs problem tho
- oh they use . for function composition. i guess they just don't have non-list pairs?
The strings are implemented as std::wstring, which allows the language to directly manipulate Unicode strings.

ough. not utf-8? really? really?
- the implementation page talks about using std::u32string instead, which is... not better.

so yeah uh. interesting language, a lot of cool ideas. not sure i'd use it myself, but it's definitely neat. also, a built-in editor is very fancy and cool.
