I see where you are coming from.  And since your approach also covers
the world of references and prefixes and whatever, it already shows
where a "simple" let container comes up short.

Uhm, I realize that I'm not helping anybody by agreeing and
disagreeing with you and Peter and even my past self back and forth.

To me <let> is the correct solution that may need to get extended to
cover additional cases.  Your task that generates unique names has
merits of its own and independent of that.  Your (much simpler)
approach would need an additional cleanup mode to get rid of my
concerns and you are already willing to provide that.

Should we follow both routes - maybe on different time scales and
branches?  Will it be too confusing for our users to offer two
solutions to the same problem?  Are we happy with a <cleanup> task
that can unset properties (and thus subvert immutability)?
