Hi everyone,
few questions:

   1. fast_perfect_hash achieves performance(load factor) I would assume is
   impossible, based on perfect hashing talk
   <https://www.youtube.com/watch?v=yOo6GnbKzp8>. I presume reason why it
   works so well that compiler places type info data clustered in same region
   of addresses... Is that correct?
   2. regarding static_list: would Boost.Intrusive list work here also, and
   if so was this considered?
   3. basic_error_output does not seem to need the Policy template
   parameter, is this left for consistency or am I wrong that it is not needed?
   4. dynamic_cast_ref docs
   <https://github.com/jll63/Boost.OpenMethod/blob/ea7dbe86b511797f0281ef07b3ada645fe569328/doc/custom_rtti.adoc>
   mention that D must match the reference category of B. Would it be possible
   to static_assert that?
