At least half the times I've shown object destructuring or module import renaming syntax
I've gotten "don't you have that backwards?" remarks. I can't say I have a
better recommendation for the general object destructuring syntax, but I expect this to
be a point of significant confusion for newcomers to ES6.
We've rehashed this a lot, so I'm going to rehash a point that helps:
most object patterns do not need to rename, so use the shorthand:
let {x, y} = somePoint;
The renaming case as you say cannot reverse property name and binding
name (or general LHS in assignments rather than declarations) roles.
People will learn. Mozillans have (we didn't add the short-hand until
years after adding destructuring in 2006).
Destructuring is quite popular in Mozilla XUL JS. See, e.g., Armin
Ronacher's tweet, retweeted by Bob Ippolito:

This is not worth rehashing again, rather, it's something to document
and teach.
