Object.getOwnPropertyNames() is intentionally generic: it returns the
immediate property names of an object, but it cannot make guarantees about
the contents of that object, so the type of the property names is merely
string[]. While this is technically accurate, it is also unnecessary if we
have an object with a type that we own (such as an enum).
Returns
The own property names of the object which are assigned a type
derived from the object itself.
