It can be useful in some cases and it is *certainly* cleaner than the 
wondrous hack that is a negative arity, but I'm never very fond of 
backwards compatibility breakage. I'd be more in favor of introducing a 
new method (e.g. 'arityrange') that would return a Range object. (please 
pretty please mr. core developpers)

IMHO, Range objects are underused. MatchData#offset would be so much 
nicer if it returned (a...b) instead of [a,b]

just my 2�
