SyntaxError: Illegal return statement

[cldwalker]

As reported in this issue, unable to eval in a js file because it syntax errors out. Steps to reproduce:

• git clone https://gerrit.wikimedia.org/r/p/mediawiki/services/mobileapps.git
• Try evaling this line. Evaling will start and then throw a popup: The node process exited. You get SyntaxError: 'return' outside of function You get the following exception:

SyntaxError: Illegal return statement

    at sbRequire (/Users/me/Library/Application Support/LightTable/plugins/Javascript/node/ltnodeclient.js:99:10)

    at Socket.emit (events.js:166:7)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1033:10)

Edit: Original SyntaxError fixed by 58c00b1

The fix will involve understanding how code is being involved in ltnodeclient.js. Pull requests are welcome until the core team has time to look at this
