Subject: Changes to x within x.each()

Does Ruby have defined behavior for 'each' in the following:

    x.each do |obj|
        ...
        x.change()    # This may add or remove objects from x
    end

Cases:
1) Adding or removing objects 'before' obj.
2) Adding or removing objects 'after' obj.

I'm primarily interested when x is an array.
