Comment 4 for bug 183559

I have seen discussions about this functionality being achievable by a combination of "merge" and "revert", but I think these discussions miss the point: the point of having "switch -r" is to be able to safely make experiments with time travel and parallel universes to see the effect of current changes or the point at which something breaks, then come back safely to the present current state.

I have only used CVS before, and I really miss this feature when investigating bugs; it makes it almost monkey-trivial to narrow new bugs to a single revision; and if revisions are sufficiently atomic, bugs become obvious.

Or I may be missing some point myself...
