|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
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.
