If you analyze (+ 1 1) in bootstrap, you won't get :numeric true in the form-meta in analyze-js-star*.
In regular ClojureScript, you'll get:
but in bootstrap, you'll get:
You can see this as well if you look at the Analysis section of David's "ClojureScript Next" blog post, where you get :numeric nil in the AST rather than :numeric true.
One consequence is that :invalid-arithmetic analysis diagnostics won't be emitted in bootstrapped environments.
