[boost] Re: Is this a legal approach to template definition separation

This is not strictly related to Boost, but its motivation comes from an effort to reduce compilation times for a Boost library, so I'll risk posting the question. Consider the following:

// *************** some_class_template.hpp ***************

#ifdef INCLUDE_DEFINITION # define BODY_INCLUDED 1 #else # define BODY_INCLUDED 0 #endif

#define BODY_DEFINITION(body) BOOST_PP_IF(BODY_INCLUDED,body,;)

If body has unprotected commas, this definition won't work. Jonathan
