Try to provide hints for common areas, either *interface were interface would have been better, and note incorrect capitalization (but don't be more ambitious than that, at least not today). Added code and test for cases ptrInterface.ExistingMethod ptrInterface.unexportedMethod ptrInterface.MissingMethod ptrInterface.withwRongcASEdMethod interface.withwRongcASEdMethod ptrStruct.withwRongcASEdMethod struct.withwRongcASEdMethod also included tests for related errors to check for unintentional changes and consistent wording. Somewhat simplified from previous versions to avoid second- guessing user errors, yet also biased to point out most-likely root cause. Fixes #10700 Change-Id: I16693e93cc8d8ca195e7742a222d640c262105b4 Reviewed-on: https://go-review.googlesource.com/9731 Reviewed-by: Russ Cox <rsc@golang.org>
