Another example where this isn't the case is in the String class:

    str = "abc\ndef\n"

    p str.member?("c\nd")           # => false
    p str.include?("c\nd")          # => true

    p str.member?("def")            # => false
    p str.include?("def")           # => true

    p str.member?("def\n")          # => true
    p str.include?("def\n")         # => true

Maybe I haven't learned to think enough in Ruby yet ;-),
but just now I'm getting one surprise after another ....
