Currently, we can use Hazaar\Model\Strict::get($key) with a $key specified in dot-notation to dive down into child objects to get data. However, if the child object key is not known, we would normally use Hazaar\Model\Strict::find((array)$criteria) to search for it. At the moment we can't do that with dot-notation so we can only use dot-notation to reference things with known keys.

What I would like to do, is extend the dot-notation syntax to allow for searching inside objects.

For example, I have a product type object which has an element named productNames, which is a child array object that contains objects of type ProductName. Traditionally, if we wanted to get the first product name, we could use dot-notation such as product.productNames.0.label to get the label field from the product name. Now say these names are not ordered, and we don't want the first one, we actually want one which has an element named productNameType which is a number indicating the type, and we want to find the one with type=3.

I would like to be able to use this syntax: product.productNames(productNameType=3).label to get the correct field.

This should be a relativly simple update as all the functionality is there, we just need to decode the dot-notation syntax and call find() internally when needed.
