# Aaron

[![Build Status](https://secure.travis-ci.org/BrianHicks/aaron.png)](http://travis-ci.org/BrianHicks/aaron)

Aaron adds some syntactic sugar to Python function composition.

## How?

Say you have the following functions:

```python

def add_one(n):

    return n + 1

def double(n):

    return n * 2

def ints_less_than(n):

    return range(1,n)

def product(*ns):

    result = 1

    for n in ns:

        result *= n

    return result

```

You could do something like this:

```python

def two_n_plus_one(n):

  return add_one(double(n))

def product_of_lesser_numbers(n):

  return product(*ints_less_than(n))

```

Or, you could use Aaron, decorate your functions with `composable`, and do this:

```python

two_n_plus_one = double > add_one

product_of_lesser_numbers = ints_less_than >> product

```

You've probably figured out by now that `>` is composition, and `>>` is will

splat the results into the next function.

## Aaron? What?

Yeah, the [composer](http://en.wikipedia.org/wiki/Aaron_Copland). Get it?
