I think, for consistency, range should return a list, not a string.
So 'a'..'d' should yield [ 'a', 'b', 'c', 'd' ], not 'abcd'.
Additionally, a..d should _not_ yield [ 'a', 'b', 'c', 'd' ] IMHO;
I would expect this to evaluate the variables a and d and compute the
resulting range. Perl can do the other thing, because variables
contain $@% stuff ;-) .

Ok, that's true :-)  I needed it only for numbers so far and thought
of something else yet :)
