So you're saying we should leave this out of BU2?

> one of the goal of BeanUtils2 is to provide the same functionality as
> BeanUtils1. In BeanUtils1 you can do something like this:
>
> BeanUtils.getProperty(person, "address.city.zipCode");
>
> This would be translated into:
>
> person.getAddress().getCity().getZipCode();
>
> The same can be done with mapped and indexed properties:
>
> BeanUtils.getProperty(person, "contact(5).name");
>
> which would be translated to:
>
> person.getContact(5).getName();
>
> BeanUtils2 provides a fluent API where the first example would be done via:
>
> on(person).get("address").get("city").get("zipCode")
>
> and the second:
>
> on(person).getIndexed("contact").at(5).get("name")

> We are currently thinking about how we can implement the property
> expressions. We are discussing this in SANDBOX-464 [1] and there is already
> a patch. I'm currently unsure whether we should allow mixing up the fluent
> API and property expressions. The contributor makes some good examples of
> what kind of awful code could be created:
>
> on(addressBook).get("provider(google).contact[5]
> ").getMapped("address").with("home").get("street.yetAnotherNestedProperty")
>
> on the other hand I don't want to force people into doing stuff like this:
>
> String path = ...int pos = ...
> on(bean).get(path + "[" + pos + "]");
>
>
> Currently I'm tempted to allow mixing up both API styles, but I'd like to
> here your opinion first.
