It's Really Suddenly
I love to use VisualStudioCode when code with golang. but after updated to golang 1.8, vsc's intellisense(or code hinting?) suggests only "PANIC" suddenly.
but it was a known problem.
i found this issue right now. and wake my iterm up, typed
go get -u github.com/nsf/gocode (this just in case)
and now, all things fixed clearly and made my coding great again.
appreciated all internet thing. thank you.
