Yes, the docs are admittedly patchy. With you mentioning parse&generate I
ran straight to
.../parsing_and_generating.html just to find a work-in-progress page. Poked
here and there. Often the same. That's OK I can wait. I hope you'll keep all
this lexical_cast/convert noise in mind when filling in the blanks. :-)

Thanks. Will do.

Is it possible to have something like
convert<int>::from()
convert<user_type>::from()
(we do not need 'to' with the interface).

For more powerful constructs my preference will probably be to "use Spirit
directly" literally instead of through the (likely limiting) convert
interface.
