Then comes someone who writes this: constexpr bool is_lt(const IntWrapper& a, const IntWrapper& b) { return a < b; } int main() { static_assert(is_lt(0, 1)); } In fact, it runs even when someone requests a page that you dont have a handler for.

Let's walk through this piece of code in detail. In this case, instead of receiving the boolean value of the comparison, you would want TypeScript to report an error when two different subclasses are compared.
