I had not considered that. Does loading the same file more than once
really happen often? On purpose? For what reason?
To load a file multiple times is fairly common when one is changing
and debugging the file. It would be good if this did not fool
unload-feature.
I don't think unload-feature should try to handle strange practices
where a file redefines things that come from some other file. If we
don't try to handle that, it should not be terribly hard to avoid
confusion when a tame and clean file is loaded more than once.
Well, I still think that when we are concerned about a working
unload-feature, the decisive criterion is that we want to be able to
restore the state before a load that actually first provided a
feature, and it does not really matter whether this load was initiated
by load, by an autoload, or by require.
I agree with that. If a file is well-behaved, unload-feature should
handle unloading it regardless of how the file was loaded.
That should not be too hard.
