 Type.1: Avoid casts
 
 In some cases, implicit casts between pointer types are safe and don't require you to write a specific cast expression. This rule finds instances of unnecessary casts you can safely remove.

 This rule is only applicable to pointers. It checks static casts and reinterpret casts.

+These cases are acceptable pointer conversions that shouldn't use explicit cast expressions:
 - conversion to `nullptr_t`;
 - conversion to `void*`;
 - conversion from a derived type to its base when invoking a base member function that's not hidden by the derived type.
