DataMapper ORM v1.8.2

In your first example you have 5 different statements in which you request data the current object doesn't have. How would you implement that using JOIN's? Make the code physic so it knows at the first statement that you intent to write more?

The second example shows you Datamapper will use JOIN's when it has the entire question in a single statement.

Your third statement is a repeat of the first. There you say "Oh, and I need this too". How would Datamapper know in the previous statement that you intend to ask for more data later?
