Re: How to bind a static member variable

The real code does bind other things rather than only a static member. 
So I guess I have to "reuse"the table that the class definition creates 
(is it a table that it is being created?). So... do I just fetch that 
with the method you proposed, and add my static member?

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.
