It is, as you say, a matter of preference.
I've thought for a long while that "in" should be value-based (so you can do things like "if(foo in [1,2,7,9])" instead of the not-as-nice "if([1,2,7,9].contains(foo))"), and that there should be some other way to check for the existance of a key (like "aa.hasKey(key)" or "key in aa.keys", or something like that). I need to check for values in an array much more often than I need to check for keys in an aa.
