This namespace contains annotations type checking core.async code.

End users should use typed.lib.clojure.core.async, which all types here
are qualified under.

This namespace helper macros for type checking core.async code.

Annotations are (automatically) provided by typed.ann.clojure.core.async, however
all type aliases are qualified under typed.lib.clojure.core.async,
so users should only depend on this namespace.
