Recursive tail calls

A babel plugin for performing tail call optimization in recursive functions.

Background

Tail call optimization was included in the ECMAScript 2015 language specification. However, some teams raised concerns about this feature, and therefore it is so far only supported by Safari.

Implementation

This plugin does not implement the feature as mentioned in the language specification. Rather, it aims to find all locations where a function calls itself in tail position, and rewrites those function using a loop. See examples directory for examples.
