Commando: Bubble Up Exceptions

[supertylerc]

Commando should be able to bubble up exceptions. There are use cases where we might want to immediately stop all the things if any device encounters an issue.

Can you clarify what you mean by bubble up? Do you mean handling them "somehow"?

Also, is this potentially something that could already be covered by overloading Commando.errback()?

[supertylerc]

I mean that if an exception occurs, I want it to behave like an exception instead of being captured. You had mentioned overloading errback in chat previously. I'll have a look and see.

@supertylerc The other thing is combining that with with_errors=False, right?

FWIW, I've had success overloading errback in the past. Unfortunately it's been too long to summon an example. :(
