> I am applying a transform that references properties in a class, the transformed class also implements a trait with properties. It seems that the trait transform is applied last, such that the annotation-driven AST transforms don't see 'inherited/mixed in' trait properties.
> {code}
> import groovy.transform.*
> trait T {
>     String s1
> }
> @TupleConstructor(includes='s1, s2') // only a constructor for s2 created, same applies to @EqualsAndHashCode for example.
> // @Sortable(includes='s1, s2') //  Error during @Sortable processing: tried to include unknown property 's1'
> class Bar implements T {
>     String s2
> }
> {code}
> This http://docs.groovy-lang.org/next/html/documentation/core-traits.html#_compatibility_with_ast_transformations talks about applying transforms on a trait itself, but as per above, this isn't what I'm doing.
> Is this behaviour by design, or am I missing something obvious? 
> Thanks for your help.
