using "extern ex x;" in the header file and "ex x(symbol("x"));" in the cpp file is more efficient.

The simplest way is to just declare symbols in header files (i.e., symbol x;) and to define them in one cpp-file (i.e., symbol x("x");). That is what I generally do. I am not a big fan of factories either.
Of course, I should have said "extern symbol x". However, using "extern ex x;" in the header file and "ex x(symbol("x"));" in the cpp file is more efficient.
