Don't define a class or enum and declare a variable of its type in the same statement

Reason

Mixing a type definition and the definition of another entity in the same declaration is confusing and unnecessary.

Example, bad

struct Data { /*...*/ } data{ /*...*/ };

Example, good

struct Data { /*...*/ };
Data data{ /*...*/ };

Enforcement

• Flag if the } of a class or enumeration definition is not followed by a ;. The ; is missing.
