ReturnMany - Tested with 1.9.3, may not work with 2+ (because of keyword arguments)

Little method that makes returning many values easier and better. You can access returned values via hash-like function [:name].

Add this line to your application's Gemfile:

gem 'return_many'

And then execute:

$ bundle

Or install it yourself as:

$ gem install return_many

You have to require gem:

require 'return_many'

And you can include (module) whenever you want.
If you require it outside any module/class it will be avaible globally.

include ReturnMany

Now you can use it via many function:

def qux
  return many a: 1, b: 2, c: 3 # and so on
end

# lets create little function, so I don‘t have to make a lot of function-examples
# it takes and returns arguments:
def foo args
    return many args
end

a, b = foo a: 1, b: 2
# a = 1; b = 2

c will have the 3rd+ args a, b, *c = foo a: 1, b: 2, c: 3, d: 4 # a = 1; b = 2; c = [3, 4]

Takes only a and c

a, c = foo( a: 1, b: 2, c: 3 )[:a, :c]
# a = 1; c = 3

Takes selected return values as array:

a = foo( a: 1, b: 2, c: 3)[:a, :c]
# a = [1, 3]

Returns modyfied hash:

a = foo( a: 1, b: 2)
# a= {:a=>1, :b=>2}

So you can do the same thing as above: a[:a, :b, :b]
