This check flags all use of c-style casts that perform a static_cast
downcast, const_cast, or reinterpret_cast.
Use of these casts can violate type safety and cause the program to
variable that is actually of type X to be accessed as if it were of an
unrelated type Z. Note that a C-style (T)expression cast means to
the first of the following that is possible: a const_cast, a
static_cast followed by a const_cast, a reinterpret_cast, or a
reinterpret_cast followed by a const_cast. This rule bans (T)expression
only when used to perform an unsafe cast.
This rule is part of the "Type safety" profile of the C++ Core
