Done some experimenting and I'm quite impressed! I've done some tinkering with one of the
Mutable templates and I've managed to remove constructors from generated classes (I prefer
using repositories, and it likes to throw Collections in as parameters) and have Collections
be eagerly initialised, preventing the possibility of null pointers.

I do have a couple of concerns (can't see a way to declare a class as abstract, no support
for adding your own methods without them getting overwritten upon re-generation) but I'm liking
this so far and will definitely bring it up with my supervisor when we meet early next week.

As for advantages, I think adding in referential integrity to associates (using the mutual
registration pattern) and implementing a way to add validate methods to operations could be
useful for generating classes for Isis, and I believe both should be doable.

Thank you so much for introducing me to this!
