Remove blanket silencing of "type annotation needed" errors Remove blanket check for existence of other errors before emitting "type annotation needed" errors, and add some eager checks to avoid adding obligations when they refer to types that reference `[type error]` in order to reduce unneded errors. 2019-09-24 18:05:49 +00:00
