# Stuck with Python but you actually want to use Haskell?

This is a silly package that (ab)uses Python operator overloading to reproduce beloved features from functional programming.

You can do:

**Currying**

```python

@curry

def f(a, b, c):

  return a + b + c

  

f(1, 2, 3)

Out[0]: 6

g = f << 1

g << 2 << 3

Out[1]:  6

f << 1 << 2 <<< 3

Out[2]: 6

```

**Infix Notation**

```python

@infix

def plus(a, b):

  return a + b

  

1 |plus| 2

Out[0]: 3

```

**Functional Programming!**

```python

@curry

def foldl(fn, x, xs):

    return x if not xs else foldl << fn << (x |fn| xs[0]) << xs[1:]

    

sum = foldl << plus << 0

sum([1, 2, 3])

Out[0]: 6

```

## Installation

```pip install pyskell```
