4020,regex::match_results::format  functor cannot use member variables,Keith MacDonald <keith@…>,John Maddock,"regex::match_results::format makes a copy of its functor argument.  This is restrictive, because it prevents the functor from managing its state using member variables.  Is that intentional?

The attached VC++ 2008 code demonstrates the problem.  When it uses a member variable to maintain a count, its output is:

(1)The (1)quick (1)brown (1)fox (1)jumped (1)over (1)the (1)lazy (1)dog

Making the counter global instead gives the correct output:

(1)The (2)quick (3)brown (4)fox (5)jumped (6)over (7)the (8)lazy (9)dog
