Testing the prototype, i've seen myself using -> null instead of a classical
empty method body when i want to have a method that does nothing.
class A {
void f() -> null;
// versus
void f() {
}
}
the compiler translates the concise version to aconst_null pop return instead
of a plain return.
Obviously, in the real world, people doesn't write empty methods all the time
and i'm not sure if it's that important, anyway i think that question should be
raised, should we want to support this a pattern ?
