There is a reason to take advantage of compilers provide nice type_info
names:you see the actual class of the exception that was thrown (e.g.
boost::lexical_cast::bad_cast), rather than the nearest base that happened
to be coded in the catch list.  Of course, that advantage isn't worth
forsaking compilers with lower QOI that provide yucky names.

Hmmm.  I guess I'd handle both, since it's only 7 or so extra lines in
test_main for the ifdefs and the typeinfo-based catch.  Anyone for
BOOST_MANGLED_TYPE_INFO_NAMES?
