Thanks for exploring new possibilities.

You are not advocating but the unit test must be written in C++.
I don't think it is a good idea to force people to write and maintain the tests
in a different language than the code it tests.

It would be interesting to better describe in details what is missing currently
and what such a framework can bring.
(I agree there is a huge room for improvements on unit tests)
