The ASTTransformer
class is designed to handle the abstract
syntax trees that Sequel uses internally and
produce modified copies of them. By itself it only produces a straight
copy. It's designed to be subclassed and have subclasses returned modified
copies of the specific nodes that need to be modified.
Return obj
or a potentially transformed version of it.
