      I agree RTTI *should* be the tool for this, but unfortunately, 
there are no guaranty that the string associated by the RTTI system with 
the type be anything (humanly) sensible. Furthermore, it may (IIRC) 
alias types, which is something I want to avoid here. That's why having 
this functionality, so as to work in tandem with 
BOOST_TEST_CASE_TEMPLATE, appear in a Boost.Test header, would be a good 
thing.

      I know I will have to buy it, I know I will have to find the time 
to read it ;-)  .
