I think ultralight scripting languages are an interesting quadrant of language space, but I'm not sure the strengths of Lisp would be evident in a language without lists.
Fair point. Perhaps "Lisp" would be a misnomer, but I do think there's value in an S-expression-based scripting/configuration language even if that language doesn't insist on revolving entirely around linked lists and the semantics/quirks thereof. Seems like vectors/tuples/structs should be just as valid as lists for a program to represent itself.
