This is quite similar to what I was going to implement.

If you store checker as a member then the size would certainly be increased
even if checker_t is empty. I'm going to use
boost::compressed_pair<value_type, checker_t> to avoid this. I could
privately inherit from checker_t instead, but I want the value_type member
sub-object to be the first in the object to optimise access to it.
