[v0.3.0-pre] cannot read property 'name' of undefined

[59naga]

The following code tries to access an invalid path property, and exit it.

/// index.js
var _createClass=function(){function t(e,r){for(var n=0;n<r.length;n++){var t=r[n];t.enumerable=t.enumerable||!1,t.configurable=!0,"value"in t&&(t.writable=!0),Object.defineProperty(e,t.key,t)}}return function(e,r,n){return r&&t(e.prototype,r),n&&t(e,n),e}}();

babel index.js
#      TypeError: unknown: Cannot read property 'name' of undefined
