Subject Confused about COGroup semantic
Date Thu, 15 May 2008 23:16:41 GMT
Normally we do COGroup like this:-

X = COGroup A By $0, B By $0 ;

This first column of the output will be data atom.

But if we do:-

X = COGroup A By $0, B By $0, $1 ;

What is the the first column then? I assume the B grouping will be wrapped
to tuple and treated as atom. Am I right?
