[Dbix-class] dirty-flag on inflated columns

[Morgon Hed]

Thanks!

One thing though:

I want the deflated object to mark the column as dirty, so to use "make_column_dirty" I need to keep a ref to the row in the inflated object.

So now the row would have ref to the object and the object back to the row ... so I have to be careful about not leaking memory with circular refs.

What is best practice in such cases? Weaken the ref to the row that the objects keeps?

Many thanks!
