Would it be possible to add a failing test folder ?

[MatthieuHernandez]

I think it would be a big advantage to be able to add tests that fail, a bit like xfail in Python.
Could there be a directory in the repo that lists tests that don't currently pass but should and will be fixed soon? (Even new features)
In my opinion, it would be simpler than having links to godbolt.org in Issues section.
It would also give people who'd like to contribute to cppfront a list of things they can help with.

What do you think of the idea?
