I'm very surprised to hear that... perhaps you used the default MSVC++ settings which IIRC don't include RTTI?
RTTI defaults to "On" since msvc++ 8.0 ... ...and yes with rtti on boost::function<> still produced a larger binary... msvc++ tr1 function<> did add one or two rtti records more (if rtti is left enabled) but, as i elaborated in my first post, it turns out this is actually a less important issue (relatively speaking)...maybe it would become more important for projects/binaries with a large number of different function<> instantiations (comparing to the relatively few i tested with) because the much more complex/'bloated' boost::function<> 'throw bad_function_call' machinery (as compared to the same 'machinery' in mscv++ tr1 function<>) would become less important (as atleast some parts of it are 'allocated' only once/not part of the template)...but the template bloat issues i outlined in my first post would still prevail significantly (over a larger number of rtti records, which can be turned off if you do not use rtti otherwise)... ps. i don't know, is a topic name change in order? like a request for a mini review or something... -- "That men do not learn very much from the lessons of history is the most important of all the lessons of history."
