+/**
+ * What would a completely transparent weave be? Is there a minimal subset that makes sense? What is the roadmap to get there? What
+ * needs testing
+ * 
+ * --- 'Transparent' here is meaning that the resultant bytecode is more representative of the original declarations, so that it
+ * looks like the intertype declaration and associated constructs have been seamless added to the affected targets.
+ * 
+ * 
+ * Fully transparent weaving, what would we like to have: - ITDs appear exactly as declared: 'private int A.i' will create 'private
+ * int i' in A
+ * 
+ * - What is the benefit? - although this isn't really in keeping with the AspectJ definition of what an ITD represents, having the
+ * end result look like the declaration does make it easier for users simply looking at the resultant class file or attempting
+ * reflection to access what they just ITD'd in place
+ * 
+ * 
+ * testing For transparent weaving of ITD fields - annotations on new fields - AJDT model - AjType support - what happens to it? -
+ * advice on within() how does that get affected? - visibility - accessors created when required? - handling clashes with existing
+ * fields - handling clashes with other aspects - generic declarations - interface declarations - initializers - static and
+ * non-static - accessibility from advice, for read and write
+ * 
+ * Design<br>
+ * The intention will be 'new code' uses the new style whilst old code continues to cause the old code to be built. Whether the code
+ * wants to use the old or new naming should be apparent from the
+ *
