Beware!  Suppose you have this:

        rule my-helper ( ........... )
        {
                my-helper-aux .....
        }
        rule my-helper-aux ( ... )
        {
             local mod = [ CALLER_MODULE ] ;
             module $(mod)
             {
                 use-project $(id) : $(dir) ;
             }
        }

Then things won't work quite as nicely. That's why I'm suggesting
to use project.current together with project.module -- this does
not depend on the immediate caller.
