I think this is a very general point: Any statistical routine should
return its results in r() or in e().

It does not really matter how exactly a program returns its results
as long as it returns them at all. The vif command, for example,
uses r()-scalars for the vif-values and r()-macros for the variable
names. This is perfectly fine. However, a matrix would be okay, too.
In case of -pcorr2- I would prefer using matrices (row vectors, to be
precise), since two statistics (partial correlations and semipartial
correlations) are to be returned.
