## About

Parametric Mixins provides an easy means to "functionalize" modules.

The module can then be differentiated upon usage according to the

parameters provided.

## Usage

Here is the most basic example. It simply makes the parametric module's

parameters available at the instance level.

    module M

      include Paramix::Parametric

      paramaterized do |params|

        define_method :params do

          params

        end

      end

      def hello

        "Hello, %s!" % [params[:name]]

      end

    end

    class X

      include M[:name=>'Charlie']

    end

    X.new.hello  #=> 'Hello, Charlie!'

Because the +parameterized+ method defines a block that is evaluated in the

context of a new Parametric::Mixin, it is possible to work with the parameters

in more versitle ways. Here is a simple example that uses a parameter to

define a method and another parameter to define it's return value.

    module M

      include Paramix::Parametric

      paramaterized do |params|

        define_method params[:name] do

          params[:value]

        end

      end

    end

    class X

      include M[:name=>'foo', :value='bar']

    end

    X.new.foo  #=> 'bar'
