Checking the possibility of converting one interface to another in Go

You need to understand what result the program will produce. Question: Is it permissible to perform a type assertion from one interface to another, and will this lead to a panic at runtime, or will the methods be successfully called?

 type Foo struct{}

 func (f *Foo) A() {}
 func (f *Foo) B() {}
 func (f *Foo) C() {}

 type AB interface {
   A()
   B()
 }

 type BC interface {
   B()
   C()
 }

 func main() {
   var a int
   var f AB = &Foo{}
   y := f.(BC) // will this type assertion work?
   y.A()       // and this call?
   _ = y
 }
