ES6 features requiring "use strict" fails while instrumenting #525

Open cosmosgenius opened 9 years ago

cosmosgenius commented 9 years ago

I am running node v4.0.0 on windows 10 x64 using mocha as the test runner. The code executes fine on node as well as mocha tests are passing when not running with blanket.

File: db.js

"use strict"
let mongoose = require("mongoose");
module.export = mongoose;

Error:

d:\Projects\github\webhooked\node_modules\blanket\src\index.js:167
                            throw new Error("BLANKET-Error parsing instrumented code: "+err);
                            ^
