# Curry

Implementation of Currying for Julia. https://en.wikipedia.org/wiki/Currying

Convert a function that accepts multiple arguments into an equivalent chain of single argument functions. Functions are chained as single argument anonymous functions that return single argument functions.

If multiple arities of a function exist, the one with the least number of arguments greater than 1 will be curried.

e.g. arities 1 and greater than 2 exist for -, but arity 2 will be choosen for currying.

Exports the following functions:

`curry`

`partial`

`swap`

Implements the following puns:

`๐`

(exported)`โ`

Examples:

```
# convert from 0-based array to 1-based. I use this all the time.
julia> ๐(+)(1).([0,1,2,3]) |> show
[1, 2, 3, 4]
julia> curry(map)(sqrt)(1:4)
4-element Array{Float64,1}:
