[TRUNCATE]

I saw a note from someone who is proposing an alternate to the boost::any
class:

*   Should call_traits be used for templated assignment/construction?  [No,
some searching in the boost mailing list suggested that it was an obsolete
optimization, and likely didn't make a difference anymore]

but I don't know how accurate it is, or if it's applicable to non-member
function templates.
