My point is that I don't want to have to use Range#to_a explicitly but
not String#to_a, nor the other way around.  In other words, I don't
want *(0...10) to do one thing and *"a\nb" to do another.  It's not
that I'm hung up on consistency per se (lots of cool Ruby things come
from inconsistency :-) but I don't like things where there are two
cases and no clear reason why, so you have to memorize them
individually.
