Does JavaElementVisitor visit expressions and statements in order of operation
(that is, the order that they would be executed / evaluated)?
Is there a simple way to resolve a reference expression to the element being
referenced? What should be passed to a PsiResolveHelper for "context"?
Is there a page with recommended methods of doing certain things with PSI?
For example, I want to synthesize expressions, such as "A == B", but where
A and B are specific PsiElement instances. (It will not be added to the PSI
tree, it's only for internal use.) Is there documentation for how something
like this should be done?
