I've noticed a strange behavior (I don't want to say it's a bug):

Normally, you use data this way:

>>> $('body').data('foo', 'bar')
[body.jq-enhanced]
>>> $('body').data('foo')
"bar"
>>> $('body > div').data('foo')
null

– everything's fine, other elements are not affected.

However if one uses it as follows, which is not that digressive IMHO (at least it was how I used it without thinking about it), everything seems also fine: …

>>> $('body').data['foo'] = 'bar'
"bar"
>>> $('body').data['foo']
"bar"

… until here:

>>> $('body > div').data['foo']
"bar"

As I said, I know this is not a bug, and I understand where the behavior comes from – all

data

[]

But nonetheless, I want to ask whether something can be done here to avoid this mistake, which is somehow self-evident and, I assume, made often. (It took me a looong time to find out that this was the reason :-) )
