1) I notice from http://svn.boost.org/svn/boost/sandbox/local/libs/local/doc/html/boost_local... that (proposed) Boost.Local has a dependency on Boost.ScopeExit. It seems that Boost.Local provides all the functionality of Boost.ScopeExit, and then some; at least, that's what seems to be implied by http://svn.boost.org/svn/boost/sandbox/local/libs/local/doc/html/boost_local... It would seem reasonable then, maybe, should Boost.Local be accepted, to remove the dependence on Boost.ScopeExit and officially deprecate Boost.ScopeExit in favor of Boost.Local's BOOST_LOCAL_EXIT: http://svn.boost.org/svn/boost/sandbox/local/libs/local/doc/html/boost_local... What are your (you = Lorenzo or anyone else) thoughts regarding that development path? 2) I haven't read through the docs in *too* much detail yet, but I would guess from, for example, http://svn.boost.org/svn/boost/sandbox/local/libs/local/doc/html/boost_local... that copying a Boost.Local functor amounts to something less than a deep copy, and possibly an entirely shallow copy. In other words, does int x = 0; void BOOST_LOCAL_FUNCTION_PARAMS( bind(int) x ) { // bind x by value, so a copy is taken... std::cout << ++x << std::endl; } BOOST_LOCAL_FUNCTION_NAME(f) boost::function< void ( ) > g(f); f(); g(); print "1" followed by "2" (my guess), or does it print "1" twice? I may have missed it entirely, but I'd like the semantics of copying a Boost.Local functor explicitly spelled out. P.S.: I noticed in http://svn.boost.org/svn/boost/sandbox/local/libs/local/doc/html/boost_local... a misspelling in the comments of the last example, s/BOOST_IDENTITY_VALE/BOOST_IDENTITY_VALUE/. - Jeff
