yes, in case of get_user_group, result is assigned to an avp and in
dp_translate result is assigned to a pseudo variable that can be an avp,
script var or two core pseudo vars.  

if you look at the code of dp_translate, you will see quite complicated
testing and what to do depending on which kind of pseudo variable is
receiving the result.  it makes little sense that each module includes
similar tests, case statements, and do_action calls.

what i tried to suggest is that pvar.h would include a function that can
be used to set a value to ANY kind of pseudo variable provided that the
pv is such that it can be assigned a new value.
