Hello, while refactoring some code I encountered something strange regarding redeclarations.
Here is an example: https://play.golang.org/p/b7Bp2w2fWwk Somehow after redeclaring err when calling doIt, err is apparently not nil, yet the functions never return anything other than nil. If I use a new variable it obviously works correctly. If I change doIt to return an error interface instead of *foo it works too. I scratched my head for a good 10 minutes to understand why something which appears nil would fail in a `if err != nil` check, so if someone has an explanation as to what's happening that would be great. Thanks. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
