I think this is an excellent idea although one could argue with
"unsurpassed graphical system" (name a system that is worse at this) and
with "powerful macro language".  What is really needed is a parser for
complex DATA steps, as more analysts have problems recoding and
manipulating data than with figuring out the syntax for lm, glm, etc. 
Does sas2R correctly handle complex DATA steps with MERGE, SET, OUTPUT,
IF, etc.?
