blue’s surface syntax.
Blue is a general-purpose language whose surface is Ruby/Elixir-shaped
and whose program is a tatara-lisp value. This crate is the join:
it lexes blue source and parses it directly into tatara_lisp::Sexp.
There is deliberately no private blue AST in between. Tenet 1 of
theory/BLUE.md is that blue source parses to tatara-lisp, and an
intermediate tree would make homoiconicity a conversion step rather
than an identity — the difference between blue’s macro story working
and merely being asserted.
