Arrows!

This is all I've got so far.

                           defmacro ~>>(left, right)

Much like the standard pipe operator |>, but threads the value resulting from
evaluation of the left-hand expression into the position after the last given
argument in the right-hand expression's function call.

## Examples

┃   # Note: The standard pipe operator `|>` would return 0.5
┃   #       in the example below.
┃
┃   iex> 2 ~>> div(4)
┃   2.0

The Future

I'd like to take a look at implementing the Swiss Arrows ideas from Robert Levy's Clojure library.

Right now this is just a bit of fooling around.

A note about the name

Lelepua is the Hawaiian word for arrow flight. Or, at least it is according to the internet.
