Imported package name as a name identifier

Reports declarations of variables, arguments or functions that overlap with the used import.

While legal, such declarations will make using the package exported identifiers impossible after the declaration or create confusion when reading the code.

Example:

import "fmt"
import _ "fmt"
import iio "io"

func _() {
 fmt.Println("demo")
 demo := true
 _, _ = iio.EOF, demo
}

func demo() (int, int) {
 return 1, 2
}

func _() {
 _, _ = iio.EOF, demo
 fmt := "demo"
 iio := 1
 _, _ = iio, fmt
 a, _ := demo()
 _ = a
}

Variable names fmt and iio clash with names of import packages. Not to confuse them later in code, it is better to rename these variables.
