== What?

Just some hax that I use.

== Contents

* Let-in - a neat syntax that's a bit like haskell. Contents of the hash supplied to `let()`
  are defined as functions on a container, on which the block passed to `in` is instance_eval'd with.

  let( :awesome => proc { |n| "#{n} is awesome." }).in { [1,2,3].map { |e|  awesome(e) }
 
  It can also be used to create mini dsl things like this:
 
  def add a
    let(:to => proc { |b| b + a })
  end

  add(5).to(3) # <= 8  
  
  
* Strucked - a class builder, that just instantiates instance vars
  
  # before
  class Foo
    def initialize a, b
      @a = a
      @b = b
    end
  end
  
  # after
  class Foo < Strucked.build(:a, :b)
  end
  
  # with readers
  class Foo < Strucked.build(:a, :b).with_readers
  end
  
  Foo.new(5, 10).a # <= 5
  
* Kernel#either - a kind of either-like thing.

  # If no exceptions are thrown, `failure` will be nil and `success` will be the result of the block.
  # Otherwise, success will be nil and failure will hold the exception
  success, failure = either {
    raise "fail"
  }
  failure # <= RuntimeError('fail')
  
  success, failure = either { 5 }
  success # <= 5
