> 14.22. Unreachable Statements
>
> It is a compile-time error if a statement cannot be executed because it is unreachable.
>
> This section is devoted to a precise explanation of the word "reachable."
> The idea is that there must be some possible execution path
> from the beginning of the constructor, method, instance initializer, or static initializer
> that contains the statement to the statement itself.
> The analysis takes into account the structure of statements.
> Except for the special treatment of while, do, and for statements
> whose condition expression has the constant value true,
> the values of expressions are not taken into account in the flow analysis.
