      Even though its only been a couple of months since this talk, I have put some improvements into plastic, with more coming. The big one is that instance fields are no longer required to be private; if a field is transformed in some way (say, providing a conduit, or an injection), it must be private, protected, or package private. If a field is not affected (say, a final field), it may now even be public. This is available in Tapestry 5.3.2 (the current stable release) and in 5.4.
