title: Import from the same package, using package name
body: <p>I've added dependency to <a href="https://github.com/sjwhitworth/golearn" rel="nofollow noreferrer">https://github.com/sjwhitworth/golearn</a> in Golang project. I've tried to build application, however I am getting error from one of the classes from <code>golearn</code> - this one: <a href="https://github.com/sjwhitworth/golearn/blob/master/base/dataframe_go.go" rel="nofollow noreferrer">https://github.com/sjwhitworth/golearn/blob/master/base/dataframe_go.go</a> : <code>undefined: base</code>. I've tried to find what is the <code>base</code> package refering to. There is no imported package <code>base</code> in this file so it looks like it is import from the same package but using the package name. I mean, dataframe_go.go is in the same package (<code>base</code>) where is the imported struct (<code>FixedDataGrid</code>). How to solve this import issue?</p>
