No, firing from the hip as usual.

I think I'd noticed repeated items in Skip's example rows.

In practice,  he wouldn't know in advance the amount of redundancy in his data,

so it's worth considering whether   ~.    is required in a particular case,  and if so

where to apply it.


Cheers,

Mike

That said, if you know of cases where these assumptions do not hold,
I'd be interested in hearing about them.
