示例1: builtin

func (f *Finder) builtin(obj *types.Builtin, sig *types.Signature, args []ast.Expr, T types.Type) types.Type {
	switch obj.Name() {
	case "make", "new":
		// skip the type operand
		for _, arg := range args[1:] {
			f.expr(arg)
		}

	case "append":
		s := f.expr(args[0])
		if _, ok := args[len(args)-1].(*ast.Ellipsis); ok && len(args) == 2 {
			// append(x, y...)   including append([]byte, "foo"...)
			f.expr(args[1])
		} else {
			// append(x, y, z)
			tElem := s.Underlying().(*types.Slice).Elem()
			for _, arg := range args[1:] {
				f.assign(tElem, f.expr(arg))
			}
		}

	case "delete":
		m := f.expr(args[0])
		k := f.expr(args[1])
		f.assign(m.Underlying().(*types.Map).Key(), k)

	default:
		// ordinary call
