Hard to Catch Error

Simply referencing the value apparently doesn't raise an error. But enumerating the rows does.

What happens if you do this?

try Table.Buffer(Data)

This should force the enumeration of the rows.

EDIT: Note that there may be other less-expensive ways to initiate enumeration. Buffering is just the first thing that came to mind.

Thanks, Ehren.

For triggering the enumeration with minimum expense, I'm attracted to "Data{0}?", based on the thought that it has the advantage of only pulling at most one row—just enough to cause the error to be raised.
