> I'm trying to build a substrate that people can fork off for new languages

I sense a common (albeit very general) theme with Readwarp. :)

> As I go over arc's functions and macros, I see a few things that just macros won't fix: if and cond treat () as false; if, + and map can take any number of args; car and cdr don't barf on (); let needs fewer parens and can handle destructuring more transparently. In these cases I plan to make it easy to just replace if with my-if in the transform phase.

Must be misunderstanding you here. I thought most of these (esp. 'nil and '() both being false, those utilities taking any number of args) were well-publicized features of Arc, not bugs. Were you perhaps referring to PLT's functions, or could you otherwise clarify please?

I love doing this.

Definitely an interesting project. I'm glad you decided to share about it here and sorry for not providing richer feedback on the actual idea in this comment.

Yeah each of these is absolutely an improvement. I meant that these are the reasons arc needs to be a language with a compiler rather than a macro library. So they're the parts that are challenging to reimplement without building a monolithic cond.
