--------------------------------------------------+-------------------------
 Doing a lexical_cast to a tuple does not work, because lexical_cast clears
 the skipws flag.

 The issue is described in the FAQ for lexical_cast:
 http://www.boost.org/doc/libs/1_35_0/libs/conversion/lexical_cast.htm#faq


 The tuple's operator>> apparently needs to set the iostate appropriately.
