When browsers implement ES6 template strings, add tags XRegExp.r (regex as raw string) and XRegExp.rx (regex with implicit free-spacing, as raw string). Don't need tag XRegExp.raw (raw string), because you should be able to use, e.g., XRegExp(String.raw\w). Don't need to support flags /gy (which XRegExp doesn't allow in mode modifiers) with XRegExp.r/rx, since XRegExp methods provide alternate mechanisms for /gy (scope 'all', the sticky option, lack of need for lastIndex updating, and the XRegExp.globalize method if you really need it). All other flags (e.g., /im and custom flags /snxA) can be applied via a leading mode modifier (e.g., XRegExp.r(?s).).

If the above sounds confusing, keep in mind that you can simply maintain the status quo but still gain the benefits of raw multiline template strings (no more double escaping!) via, e.g.,

Good-bye constructor functions?

tl;dr

Constructor function were workaround to specify constructor for a class without class. Now, having class nothing presribes the class being equivalent to its constructor. It always brought confusion and now with constructor empowered, it brings two-space problem. The class keyword can return plain objects, which have [[Construct]] calling the constructor of the class.

function evaluate(context, expr, origExpr, onSuccess, onError)

    var result;
    var commandLine = createFirebugCommandLine(context, win);
    // gets the debuggee object: 
    var dglobal = DebuggerLib.getDebuggeeGlobal(context.window, context);

    // that works:
    commandLine.someFunction = dglobal.makeDebuggeeValue(function()

CIS claims 72 terrorists have come to the US from the 7 countries in Trump's travel ban. Here's what I learned.

• These cases aren't about actual attacks in the U.S. The Ninth Circuit said "The Government has pointed to no evidence that any alien from any of the countries named in the Order has perpetrated a terrorist attack in the United States." The reason I got into this mess is people claiming the court lied. They did not lie. Nor is CIS lying. This list is mainly people who aided terrorist groups, and a few FBI sting operations. In all 11 cases I got to, no attack occurred.

• These people were not all admitted to the U.S. under current vetting procedures. See the last case listed below.

Cases

I had an hour to spend. I looked into these cases, mostly relying on news accounts.
