There is such a warning reported from golint : exported var ChangeState should have comment or be unexported
however it's not detected by arc lint, not sure what's the reason behind this
Steps to reproduce:
install the latest arcanist from github
create test.go with following content
```package test
var (
Test = 47
)```
try golint test.go, output:`test.go:4:2: exported var Test should have comment or be unexported`
try arc lint, output: `OKAY No lint warnings.`
