 `rtl::CxxMirror` returns two reflection metadata objects: `rtl::Record` for any registered type (class, struct, or POD) and `rtl::Function` for non-member functions.
 
 From `rtl::Record`, registered member functions can be obtained as `rtl::Method`. These are metadata descriptors, not callables. Callable entities – i.e., functors, are produced by explicitly providing the argument types we intend to pass.
