Only the last binding is respected in case of multiple bindings with same type

[Hritik14]

Consider this:

	my_name := "Alice"
	your_name := "bob"

	ctx := kong.Parse(&cli,
		kong.Vars{
			"version": "0.0.1",
		},
		kong.Bind(my_name, your_name),
	)

func (cmd *BuildCmd) Run(my_name, your_name string, globals *Globals) error {
	fmt.Println("my_name " + my_name + " your_name: " + your_name)
	return nil
}

and run

; ./main build a
my_name bob your_name: bob

This happens because bindings are attached via

kong/callbacks.go

Lines 123 to 125 in 8d238c8

	for i := 0; i < t.NumIn(); i++ {
	pt := t.In(i)
	argf, ok := bindings[pt]

and bindings is a map

kong/callbacks.go

Line 12 in 8d238c8

type bindings map[reflect.Type]any

This is working as intended. To differentiate between values of the same type you'll need to create a new type:

type MyName string
type YourName string

kong.Bind(FirstName("Alice"), YourName("Bob"))
