The above is converting a string to an int, so to_string would be
inappropriate.  I.e. string::to and to_string are grammatically different.

Ditto.
Oh, I certainly meant in reverse.

Everything looks fine with me, except that I would suggest using a more explicit
syntax for the default value specification. Like this:
boost::string::to<int>(s).with_default(-1);
boost::string::to<int>(s, _default=-1)
?
see Boost.Parameter
Yes, that's a good alternative.
