I agree that "return do" is not pretty. But I don't think it would be wise to
have two forms of FLWOR, one that requires an updating expression and one that
requires a non-updating expression. This will get us into trouble later if we
allow updating expressions and non-updating expressions to be mixed, as in the
XQueryP proposal. I think it is wiser to keep the FLWOR expression fully
orthogonal (independent of what kind of expression is in the return clause).

Note that this issue (relationship between FLWOR and updating expressions) was
discussed at great length at the St. Petersburg meeting of the working group in
January 2006. The current design was agreed upon by the working group after
considering several proposals. One of the things that slows down our progress
is repeatedly revisiting decisions that were made explicitly many months ago.
