Maybe I don't understand the problem ...
I assume address.e will contain functions and procedures, why should
they be duplicated? The same functions and procedures can work on
different data, so what's wrong with the "classic" approach:

-------------------------------------------------------------
include address.e   -- say it defines a global type address,
                    --   global constants SIZEOF_ADDRESS,
                    --   NAME, ...

address customer, vendor, company

customer = repeat(0, SIZEOF_ADDRESS)
vendor   = repeat(0, SIZEOF_ADDRESS)
company  = repeat(0, SIZEOF_ADDRESS)

customer[NAME] = "Joe Smith"
company[NAME] = "Footless Corp."
etc..
-------------------------------------------------------------
