Known Issues

• CallExpression's that uses other transforms from this preset only insert them 1 level deep due to path.unshiftContainer adding a new CallExpression in Program:exit(). Need to figure out a way to do another Program:exit() after the first if new CallExpressions have been added so state[name].matches can be += 1'd.
