Addressing the limitation of the class's private class

[schaumb]

with auto return value and decltype it can leak out the private types too. see example

(and private type private member example)

Hey, thank you for the example. It's great that we could have a work around for this limitation. I'd like to keep C++11 compatibility, but we could detect if the given compiler has the "auto return type C++14" feature and if yes then we could define the proper macros for access_private_class. Do you think you could create a PR that addresses this?

[schaumb]

I created a C++20 fork from this repo. There it can made without macro. If someone has time to work with it, backport here.

[martong]

Okay, thank you. I am extending the readme to advertise your fork for C++20.

[martong]

Umm, not closing, since at some point we could backport to C++14.
