I don't think Boost.Core is the right place for them as this library is for small generally useful components used by many libraries. The components you pointed out seem too specialized to me, and Boost.Fit looks like the right place for them.

Andrey, I was thinking in Boost.Core as these are
      language-like emulation features, like e.g. addressof, enable_if,
      explicit_operator_bool, ignorunused, no_exception_support,
      noncopyanble, scoped_enum, typeinfo.

      

      IIUC, BOOST_FIT_STATIC_FUNCTION try to fix a standard Core issue
      (pending issue 2104 in CWG) identified by Eric Nibler, with the a
      solution based on proposal's Eric
      (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4381.html).
      The library has also a macro BOOST_FIT_DECLARE_STATIC_VAR to do it
      for any data variable. I would like something that solves this
      problem in Boost.

      

      BOOST_FIT_STATIC_LAMBDA try to covers the C++17 feature constexpr
      lambdas.

      

      I suspect that Boost.Hana should have something like that. Louis,
      could you tell us how do you manage with these issues?

      

      IMO, The fiw of those issues is independent from a functional
      utilities library, even if Fit can not work without them.


      

      This is way I believe that it should be extracted and Boost.Core
      seems the good place to me.

      

      Best,

      Vicente
