How can I work out the number of global symbols introduced
per serializable type ?  Is this fixed or does it vary according
to type of serialisation , i.e by ptr, versus by value ?

On linux I tried:
    nm  test | grep GLOBAL | grep RepeatDay | wc

Which revealed about 26, however this does not seem right ?

Is there any way to reduce this overhead?

Any help appreciated.
