When tables are 'variables' you can create what I called
a 'Super Function'. Pass any table of the appropriate 'type'
to the function, it's that simple. The example was a function
that returned a dense rank including when the target column
of the rank repeats. The function assumed a single primary key.
And only the PK and the target column of the rank constituted
the table to be passed to the function.

Well it's a simple matter to overload the function for tables that
have a compound primary key. And you can envision a library of
different functions based on table 'type'.

Hopefully some will 'get' it :-)
