That Stata matrices also occupy a different memory space is (i.e. persist after memory is cleared) is another endearing feature... Useful for collecting results from different data sets into one place (among other things, I'm sure)

Yes indeed, but the difference between a Stata variable
and a Stata vector is larger in practice than in principle. 

There are ways of getting matrices into variables 
and vice versa (including, but not only, -svmat- and -mkmat-) 
but a crucial difference is that Stata variables and Stata 
matrices (vectors being a special case) are in different 
namespaces.
