babel-plugin-iife-wrap's Issues

Add directives handling

Now use strict pushed outside of iife.

(Documentation) Does this plugin add use strict or not?

I noticed that in your tests you expect use strict to have been added to the result, but this isn't mentioned in the readme.

Doesn't work with babel-plugin-transform-es2015-typeof-symbol

I made a gist to demonstrate:
https://gist.github.com/AlexanderOtavka/698b83a1ffab9b2141d01b6cd25753c7

Babel will transpile the js file just fine if either the iife-wrap plugin or the
transform-es2015-typeof-symbol plugin are commented out, but will not work
if they are both present

iife-wrap seems to make transform-es2015-typeof-symbol run twice on the same
code but I am not sure exactly what is going on

See for yourself. Download and unzip the gist, then run
npm install && npm start. It will error. Then comment out one of the two
plugins identified by my comments in the gulpfile. Try npm start again and
watch it compile successfullly, and print "symbol" as it should.
