What happened to any? in Ruby 1.9

[Tim Morgan]

OK, so I see one of my favorite string methods "any?" is now missing from Ruby 1.9. I'm hurt.

$ irb1.8
>> ''.any?
=> false
>> exit

$ irb1.9
irb(main):001:0> ''.any?
NoMethodError: undefined method `any?' for "":String
    from (irb):1
    from /usr/bin/irb1.9:12:in `<main>'
irb(main):002:0> exit

1. Why in the world would this be removed?
2. Any harm in defining it myself?
3. Is there an alternative, blessed way of determining if a string has something inside? Do I really have to change all my usage of any to !empty?

Right, so you just need to be specific about what you want to enumerate ove=
r:

>> "foo\nbar".lines.any? { |e| e =3D=3D "bar" }
=3D> true
>> "foo\nbar".chars.any? { |e| e =3D=3D "b" }
=3D> true
>> "foo\nbar".bytes.any? { |e| e =3D=3D 97 }
=3D> true
>> 97.chr
=3D> "a"
