stack commented on HADOOP-1608:
-------------------------------

I like your suggestion of a sub-shell as a means of demarcating basic operators from non-sql
relational algebra operators (Do you want to add your proposal to the wiki?)  

One question: Is 'numeric' the right term to cover all the subshell adds?  'Numeric' covers
linear algebra and matrix operators fine but do you think it encompasses relational algebra?
