Re: issues with Trellis event loops and threads

I also think there should be a way to use the actual current state in
the other thread, but context.States just doesn't work that way. I see
no reason why it has to be that way. The app can set up it's current
state and then start an operation in a new thread, it's only natural
to make sure it works in the same / child context, but with all the
"states[get_indent()]" that wouldn't work at all. Am I missing
something or is that a design defect?
