No new variables inspection should account for variable shadowing rules

[gabrielf]

The code below can run but the go plugin says it contains an error:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    ShouldAllowParameterShadowing("param")
}

func ShouldAllowParameterShadowing(i string) {
    fmt.Println(i)

    for i := 0; i < 3; i++ { // Inspection error "No new variables on left side of :="
        fmt.Println(strconv.Itoa(i))
    }
}

But it will run correctly and output:

$ go run main.go
param
0
1
2
