GroupBy for multiple columns about go-linq

Hi @yogihardi
Sure, it is possible. You may either make a typed struct or use an anonymous one.

For example:

import (
	"fmt"

	. "github.com/ahmetb/go-linq"
)

func main() {
	input := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}

	q := From(input).GroupBy(
		func(i interface{}) interface{} {
			return struct {
				col1 int
				col2 bool
			}{
				i.(int) % 2,
				i.(int) < 5,
			}
		},
		func(i interface{}) interface{} { return i.(int) })

	fmt.Println(q.Results())
}

Counting this as answered.
