Object#in?

Returns true if this object is included in the argument. Argument must be
any object which responds to +#include?+. Usage:

  characters = ["Konata", "Kagami", "Tsukasa"]
  "Konata".in?(characters) # => true

This will throw an ArgumentError if the argument doesn't respond
to +#include?+.
