FWIW, I don't see how this is a bug or even bad behavior. Other
languages work similiarly:
$ perl -le 'print -2**2'
-4
$ perl -le 'print 3-2**2'
-1
This seems like one of those "could see it either way" issues. I
personally think the Ruby behavior is consistent. Changing it could
break existing code. Using parens to disambiguate the expression works fine.
