Sorry, should have sent this to the group...
That seems a little unsatisfactory. I'm aware of the difference in terminology
of course. The problem remains that arrow functions make bind etc.
unpredictable. You're relying on the programmer to do the right thing and
that's a bad idea IMO.
Can you point me to one of the threads you mention? A quick search turned up
nothing on thus earlier, and I should read one of those to get up to speed.
