Discard all tabs in Google Chrome / Chromium

Why?

There are multiple extensions that claim to do this, but I didn't find one that was working in incognito mode.

Steps:

1. Go to chrome://discards/
2. Open the DevTools and click on the Console tab (or press [Esc])

void main()
{
    throw globalInstance!Error("This is an Error()", null);
}

T globalInstance(T, bool tls = true, Args...)(auto ref Args args)
if (is(T == class))
{
    // There really should be a trait for this:
    enum classAlignment = 2 * (void*).sizeof; // until then, here's a reasonable guess :)
