# Object#in?

A monkeypatch on Object which adds the instance method `in?`, which is

effectively the standard library `Array#include?` method with the subject

and object inverted i.e. so the object you're search for receives the method

call.

## Installation

Add this line to your application's Gemfile:

    gem 'object-in'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install object-in

You can view me on Rubygems.org [here](http://rubygems.org/gems/object-in).

## Usage

This adds to Object, so it will be available on *(essentially?)* everything.

It takes one parameter, the array you want to check for the object's inclusion

in.

```ruby

array = %w{yankee doodle doo}

"yankee".in? array # => true

"da".in? array # => false

yankee.in? array.join(" ") # => raises a TypeError exception

```

* It returns true if the array passed in includes the object.

* It returns false if the array passed in doesn't include the object.

* It raises a TypeError exception if the passed in object isn't an Array
