(path ...ValueIndexOrName)

// Index returns a new pointer to the array or field element found by following
// the list of indices as specified by path.
func (v *Value) Index(path ...ValueIndexOrName) *Value {
	if !IsPointer(v.ty) {
		fail("Index only works with pointer value types. Got %v", v.Type().TypeName())
	}
	indices, name, target := v.b.path(v.Type(), v.Name(), path...)
	return v.b.val(v.b.m.Types.Pointer(target), v.b.llvm.CreateGEP(v.llvm, indices, "")).SetName(name)
}

// Insert creates a copy of the struct or array v with the field/element at
// changed to val.
