should the following query work?

[Lin Guo]

A = load 'foo.txt' using PigStorage as (x : chararray, y : int);

B = group A by x;
C = group B by group;
describe C;

-- we got
-- C: {group: chararray,B: {group: chararray,A: {x: chararray,y: int}}}

D = foreach C generate B.(group, A);  -- this works
describe D;

E = foreach C generate B.(group, A.(x));
describe E;
--- pig returns syntax error, but should this work? Or is there a patch for it?

thanks,
lin
