C++ allows “backward” assignments by means of a dynamic_cast operator: s = dynamic_cast<bar*>(q); // performs a run-time check If the run-time check fails, s is assigned a null pointer. For backward compatibility C++ also supports traditional C-style casts of object pointers and refer...

The actual restriction is on implicit or explicit use of this—so, for example, it's fine to refer to an instance variable of another class instance passed in as a parameter, or to cast to an inner class type. We should explore what javac does here, because the rule is not clearly ...
Requires explicit cast to int32x4 or boolean8With overloaded return types we can support both signatures:const a: int32x4 = int32x4(0, 1, 2, 3) === int32x4(0, 1, 3, 2); const b: boolean8 = int32x4(0, 1, 2, 3) === int32x4(0, 1, 3, 2);For reference, the ...

Here "dynamic" has the meaning of "known only at run-time". 所以根据文档: dynamic_cast会进行动态类型检查,只有符合运行时类型的对象才能转换,转换失败会返回NULL(*)或者抛异常std::bad_cast.(&),而static_cast不会检查类型正确性。 dynamic_cast 可以classes up, down, and sideways along the inheritanc...

And IMO that is more unsafe than the type cast presented in my answer, which was only performed to allow the insertion of a field in an object. In that sense, the resulting class type C & Maker<T> should remain compatible with everything else relying on a C. I also tried picturing ...
