I don't think the nested inclusion has much chance. It assumes an inside-out process order that isn't how wagn works.
I think the way to go is a search. You can refer to _self and what is referred to in a single search and append whatever you need to. So long as you're ok with having a process where not everything is added in the initial card creation, this should work pretty smoothly for now.
Nice. Seems like it ought to work, but from http://test.dwagn.org/wagn/inclusion_in_an_inclusion (+this way) I'm guessing append doesn't accept card definitions.

switch it around. prepend "_left".

hehe, nice. anyway, ticket/idea let append and prepend accept card definitions?

Sure. Fairly low pri. *may* not be that hard to implement
