Module is a node type of variable

[tkrause]

It seems that the treesitter implementation for Go does not correctly parse modules. The module is correctly parsed when inside the function declaration.

However, when a module is used in a function or method it instead becomes a type of variable.

Example Code:

package main

import (
    "fmt"
    "time"
)

// Here time is a module
func getTime(t time.Time) string {
    return t.String()
}

func main() {
        // Here, fmt and time are variables not modules
    fmt.Println("The time is: ", getTime(time.Now()))
}

tree-sitter is not context-aware, that's what queries are for, so you can tag specific bits and correlate that with their usage later on within a scope.
