As someone who used SAS for 22 years before discovering S-PLUS
I had to use the macro "language" in SAS extensively. Macro languages
are in many ways "dead" as they are not close to the actual data
(try this in SAS: if x is discrete PROC FREQ else PROC UNIVARIATE).
What is surprising to me is that there are many people who actually
believe that macro languages are powerful languages!
Related to this, in my experience people who have never used SAS
learn S-PLUS faster than those who have.

I also second the "researchers willing to program" idea.
