In the my limited  experience of using  Boost.Typeof  as a user, I have found
that I only needed to register at most a few types (mostly mpl), and was unhappy
in the situation where the only choice is that all types in every header
dependency  known or unknown got registered.  I appreciate that in many cases
the specialisations are relatively simple  but if there is a large number of
specialisations it will eventually have a noticeable effect on compilation
times. In the case of  libraries of components such as mpl therefore, if
possible I would prefer the 1st option over the 2nd and 3rd and would be happy
to use the convention of  a directory named typeof_support (or just typeof?)
which user would add to component include path to use versions of  the component
that included typeof registration.

Of course the above approach is the most complicated, much  more fussy than
simply registering everything  at once, but  I would think that needing to
register only a few components rather than everything that might possibly need
to be registered in a particular library is the most likely requirement?

Thanks anyway for working to sort this out.
