TypeError when using ES2015 arrow functions

[jaypanares]

Hi,

Currently using ES2015 arrow functions to implement a task and I'm met with the following error:
TypeError: Cannot read property '1' of null

My gulp task:
gulp.task('test-param', (debug) => console.log(debug));
with the command:
> gulp test-param --debug

I know ES2015 may not be widely used yet but I wanted to let you know that the arrow function breaks the intended behavior.

Thanks!

hi
this could be a problem with https://github.com/stoeffel/retrieve-arguments
Will look into it as soon as possible, or maybe you want to investigate.

I confirm this, btw you can use babel and everything will work fine

npm i babel-core babel-preset-es2015 --save-dev
echo '{ "presets": ["es2015"] }' > .babelrc
mv gulpfile.js gulpfile.babel.js

Same error on my side. When I change my gulp task to use old-fashion function then everything is working as expected. Using arrow function leads to the described error above.

Any news when/if this error will be fixed?
