Hi all,
I was wondering if there is any macro in Boost.Config for advertising the defect of the "using" support from the compiler.
I was reported this:
https://github.com/boostorg/test/pull/140
and at the time I wrote the thing, I thought that those guards would have been enough:
https://github.com/boostorg/test/blob/35c9acf5bd38d625ebd45cf940c5b9a19aa229...
(auto, tuple and variadic template sounds to me more difficult to support than "using" template alias).
Would it make sense to have BOOST_NO_CXX11_TYPE_ALIAS?
Why not just use a typedef?
I would say, using a macro check would make the code less maintainable.
It is not that I do not want your PR :)
I did not intend to advocate my PR, I really wanted to know the rationale for the new macro.
Here is why
* the macro checks are already there, but apparently they did not capture all I needed. * the compiler advertises the support of several C++11 feature, but the support seams to be missing in other aspects. I would prefer removing this new feature of Boost.Test totally for such compilers as it may pull something else that I need to change, or mislead the users. * For a developer, typedef or using should be equivalent as this part of the code is C++11.
Thanks.
