I removed the restrict mode custom versions of == and !=. This shouldn’t come as a big surprise since I hinted that I wasn’t happy with clause 1 in the case for restrict mode <http://blog.lassus.se/2011/03/case-for-restrict-mode.html>. Now all of ==, !=, === and !== behave identically in normal and restrict mode and you should strongly consider not using == and != irrespective of whether you use restrict mode or not.
I relaxed the restrict mode + operator slightly. It was previously only allowed for str + str (concatenation) or num + num (addition), but never a mix. It’s now also allowed for num + str or str + num, which happens to be the most common coercing usage of it out there in the wild. I hope that this will lower the barrier of restrict mode adoption.
