The question is what (FlipSticks vs WatchMe) usecase is more usual and
what fails are more unpredictable :).

In my mind, when people are coding end applications whey should not care
about names of modules (assuming that local modules will be imported
in any case) they are creating (in case of comparing with coding libraries).

In cases like WatchMe (in my mind special cases), it is all time
possible to change sys.path in particular way before including the
rest of WatchMe code. On other side, having requirement to do something
special for regular activities, sounds overkill.
