RE: Ordering of AST transformations

[Milles, Eric (TR Technology)]

You can have a look at org.codehaus.groovy.transform.ASTTransformationVisitor, 
org.codehaus.groovy.transform.ASTTransformationCollectorCodeVisitor and 
ultimately org.codehaus.groovy.control.CompilationUnit.  The compiler phase 
operation linked lists are what you are looking to order.  Besides the phases 
for ordering, it is strictly FIFO ordering at the moment.
