# bug. and i don't see this as being at all unpredictable.

you just said you've _learned that x||=y means set x to y unless x. Surely it was _unpredictable at some point. Surely x<op>=y is a no-brainer for a many of us :)

and now we all have to update our test cases, cause maybe x += 1 may not always be x = x + 1
