The behavior of value-initializing an enum

Question

First, I want to say, according to cppreference.com, it is somewhat impossible to value-initialize an enum.

According to http://en.cppreference.com/w/cpp/language/value_

Answer 1

1: This can be undestood like so:

enum class SomeEnum : int { V1 = 0, V2 = 1, V3 = 2 }; 
SomeEnum a = 0; // compile error
SomeEnum b = SomeEnum.V1; // OK

This is basic protection from undefined behavior!

2: Yes and Yes :)

SomeEnum c = static_cast(1); // = SomeEnum.V2
SomeEnum d = static_cast(5); // undefined behavior

static_cast is dangerous by definition, it shoud only be used to support serrialization or old c interfaces!
