String Ranges

T. Onoma

11/7/2004 1:06:00 PM

I wonder if any one has ever noticed the "order" discrepancy that exists
between String#<=> and String#succ. One consequence:

irb(main):001:0> a = 'a'..'b'
=> "a".."b"
irb(main):002:0> a.include?('aa')
=> true

Also I'd like to know what others are doing with string ranges. If you've used
a string range in a serious way I'd like to know how --I'm trying to get a
impression of their over all usability.

Thanks,
T.

I've don't think I've used them without the .to_a suffix.

Ever once in a while I'll do a ('a'..'z').each { } type dealie, can't
remember why at the moment. (Of course this can be achieved with
to_a.each { } to)
