CWG2879 [expr.const.cast] Clean up specification of const_cast CWG2879 [expr.const.cast] p9 does not have a corresponding formal wording CWG2879 [expr.const.cast] p3 does not cover all cases of similar types CWG2907 [expr.const] uninitialized glvalue of type std::nullptr_t appears in the constant expression A corner case for an explicit type conversion whose type-specifier is void and the initializer is non-empty braced-init-list
CWG2894 [expr.type.conv] T{...} Functional casts create prvalues of reference type T CWG2901 [basic.lval] Accessing an object through a different type through which it is type-accessible has undefined semantics CWG2906 [expr.cond], [expr.const] Lvalue-to-rvalue conversion of class types disqualifies constant expressions CWG2905 [temp.dep.constexpr] value-dependence of noexcept ( *expression* ) CWG2910 [basic.def.odr] Effect of requirement-parameter-lists on odr-usability
