More generally speaking, if you could store table values as table fields, 
or row values as table fields, that would provide a lot of flexibility and 
power.  A Perl Hash data type could then be represented by a 2-column table 
with a unique key on one of the columns.  The array type could also be 
generalized into this as a 2-column table where one column is an integer 
with a key on it. -- Darren Duncan
