There may be a disadvantage to this if you have a saved image of the
function -- the current one will be saved, not the one that gets a bug
fixed next week. Or maybe it's okay, I don't know. I think a way
around that problem would be
which won't actually do the copying until the first use of bar.
As Romain said, if there are multiple foo functions around, just qualify
the name before importing.
