We should do something:

 (a) revert and remove Enumerable#join altogether, leaving Array#join.
 (b) make Enumerable#join not to join recursively; I think Array#join
     should remain recursive join for array elements.

Which do you guys prefer?  I don't disclose my preference now, since
disclosing mine would have too much impact on discussion.
