> ??I am not sure if this is a bug, or something more subtle, but here is the
> problem that I am having.??
> ??When I LOAD a dataset, change it with an ORDER, LIMIT it, then CROSS it
> with itself, the results are not correct. I expect to see the cross of the
> limited, ordered dataset, but instead I see the cross of the limited dataset.
> Effectively, its like the LIMIT is being excluded.??
> ??Example code follows:??
> {code}
> A = load 'foo' as (f1:int, f2:int, f3:int); B = load 'foo' as (f1:int,
> f2:int, f3:int);
> a = ORDER A BY f1 DESC;
> b = ORDER B BY f1 DESC;
> aa = LIMIT a 1;
> bb = LIMIT b 1;
> C = CROSS aa, bb;
> DUMP C;
> {code}
