Could this be a possible enhancement?

Consider the following syntax (or something similar, the assignment of a specific alias is the key):

Query query =
Ebean.find(Asset.class)
.join("attributes", "attributes.definitionId, attributes.value", "a1")
.join("attributes", "attributes.definitionId, attributes.value", "a2")
.where()
.eq("a1.definitionId", 57L)
.eq("a1.value", "Quux")
.conjunction()
.eq("a2.definitionId", 56L)
.eq("a2.value", "Foo")
.query();
