What is the correct way of checking if a type is already registered?

[JvJ]

I'm working on a project that involves generating C++ code, and there are many different aliases that end up resolving to the same type. This is causing "type already registered" errors.

I'm unsure of what is the correct way to determine whether a type is already registered.

I am currently attempting to use py::detail::get_type_info to get a py::detail::type_info structure. However, the fact that this structure is defined in a header called "internals" makes me think it's not a good idea to use it.

Is there another, better way?

I'm facing the same issue.
Is there any way to check if a type is already registered in a module?
