Take the &env from a macro, and tell whether we are expanding into CLJS.

Platform specific converters. Takes the env (from &env or platform keyword) and returns a converter function. The converter function takes a symbol and returns the platform specific version of that symbol.

An atom containing the platform specific predicates. Is an map of predicates, and their platform keyword value. The predicate should take a macro &env and return a boolean. See https://clojure.org/guides/reader_conditionals for platform keywords.

Takes the target env (from &env or platform keyword), and a quoted symbol. Transforms the symbol to platform specific symbol.

(symbol :cljs 'clojure.core.async) => cljs.core.async

Transforms the symbols in a quoted form to platform specific symbols. Takes a quoted-form to be transformed. Use this in macros. e.g. (defmacro go [& body](env/transform (async/go ~@body)))`
