Tweaked so it actually works.  ;-)

============
alert('injecting.');

unsafeWindow.location.href = 'javascript:var mytestvar=1;';

if (unsafeWindow.mytestvar) { //js enabled, continue.
  alert('i do declare!');
}

alert('done');
============

The code inside the branch will only run if the user script was
successful in setting a variable in the page context -using the page
context-.

This is different than just
unsafeWindow.mytestvar = 1
because that approach uses the chrome context's js engine, which would
succeed despite whether page scripts were enabled.

I tested this with GM and NoScript, injecting on google.com.
