Getting a syntax error running against my test suite

node --version
v7.7.1

npm --version
4.1.2

I am attempting to add Istanbul coverage to my FPO project. The qunit test suite runs fine by itself, both in node and the browser.

But when I try to run:

istanbul cover scripts/node-tests.js

...as indicated in Istanbul's docs, I get a syntax error reported:

The beginning few lines of that file being complained about are:

(function UMD(name,context,definition){
    if (typeof define === "function" && define.amd) { define(definition); }
    else if (typeof module !== "undefined" && module.exports) { module.exports = definition(); }
    else { context[name] = definition(name,context); }
})("FPO",this,function DEF(name,context){
    "use strict";

    var publicAPI = {
        identity: curryMultiple( {fn: identity, n: 1} ),
        constant: curryMultiple( {fn: constant, n: 1} ),
        pick: curryMultiple( {fn: pick, n: 2} ),

..

As you can see that code is entirely valid (ES5 even). AFAICT, it's fairly standard UMD style code. I'm not sure which : the syntax error's message is complaining about.

Other parts of that file use ES6, but it's all simple stuff and I can't see anything that would be interfering with the Esprima parsing that Istanbul does. I even ran the entire file through Esprima's online code parser and it parsed fine.

Any thoughts? Apologies if this is a known issue. I tried searching through issues, but there's a lot there and I couldn't sort out which ones to look at or not.
