Nontype Template Parameters 在 function template，我们也可以用 Nontype Template Parameters，表示我们对某个 type parameters 使用固定类型的参数。在函数实例化时，nontype template parameters 应该使用常量表达式作为参数，从而让编译器在编译期间推导出它的值。举个例子，
该类模版接受两个模版参数一个是非类型模版参数（nontype template parameter）该参数接受一个bool值，第...
The following code causes an Internal Compiler Error in VC++ 19.14.26428.1. It appears to be related to using a non-type template parameter in as the argument to noexcept in a function pointer type. As I understand, noexcept only became part of the function type in C++17. So I...
