package main
import (
        "reflect"
        "fmt"
)
type X int
func (_ X) Foo() { }
func main() {
        v := reflect.NewValue(X(0))
        fmt.Printf("%d\n", v.Type().Method(0).Type.NumIn())
        fmt.Printf("%d\n", v.Method(0).Type().(*reflect.FuncType).NumIn())
        v.Method(0).Call([]reflect.Value{reflect.NewValue(X(0))})
}

this prints:
1
1
panic: FuncValue: wrong argument count

The type of the method should return the argument count
that the method is expected to be called with.
