Ignoring package name collisions

Package name collisions occur when a variable or function shares the same name as a package.

Mistake

Package declaration

package redis

type Client struct {
	//...
}

func NewClient() *Client {
	//...
}

func (c *Client) Get(key string) (string, error) {
	// ...
}

Client implementation

redis := redis.NewClient()
v, err := redis.Get("foo")

The redis variable now makes the redis package inaccessible in this scope

Fix

Use an import alias or change the variable name.
