Any, Conversion, DLL, LexicalCast, Stacktrace, TypeIndex, Variant.

This could be usefull for Variant - it will make the library slightly
smaller and well maintainable. But not much better.

Same as above.

Not for c++11.

There are plenty.

=======Please quote till here ======================================

Actually, I'd like to go further than you propose. There's a plenty of
request to use C++17 classes in the Boost libraries I maintain.

So my idea is to start a new fork/branch of Boost that requires C++17
compatible compiler. This will allow library developers to use modern
features, experiment with them and invent cool things.

This will allow me to drop Any and Variant. This will also allow me to
* significantly improve/rewrite LexicalCast and drop the std::locale
dependency that insanely slows down the runtime
* implemet a DLL library that uses std::filesystem::path and
std::system_error without unnecessary dependencies on Boost

For the remaining libraries I'll be able to drop Config, TypeTriats and
some other dependencies. This will improve compile times and reduce LOC to

Best regards and thank you for your time
