Iterating objects with _.each is unsafe

[latentflip]

If the object being iterated can have a .length property, like attributes, .each will break. We should change to iterate over .keys explicitly

Are you talking about every available object that's being iterated? or only for a specific methods?

this._children
this._collection
this.attributes
this._derived
def.dataTypes
def.props
def.session
def.derived
def.collections
def.children

Oops I threw this in to remind me about it but didn't explain the problem very well.

In the ampersand-state code somewhere (can't check right now from my phone) we iterate this.props with .each. .each iterates over objects yielding keys and values.

However, if your props has a 'length' property, that triggers _.each to iterate it like an array (yielding index and value) which breaks everything.

You were right. It was breaking clear function :)
