yes. IIRC you can just bind your class "A", then treat _G.A as a table and just add stuff to it, like the static const value.

>>> It seems as though while functions can be registered "globally" (in a namespace rather than a class member), no such provision was made for variables/data. I've added a test here:
https://github.com/rpavlik/luabind/blob/static-members/test/test_static_member.cpp - the version committed succeeds but uncommenting the data members causes a compile failure just as you had noticed. (There is a luabind::def function that mimics the .def member of luabind::class_, but no such luabind::def_readonly...) I'm not sure if a workaround of setting the variable would work - I've had a tough time trying to figure out how to bind references to values/data to Lua with LuaBind.
