Injecting nested state value to a behavior

[pilwon]

How do you inject nested state value to a behavior? (ex: $states.get([‘a’, ‘b’] from {states: { a: { b: 1 } } })

@Imti on Slack:

We don't have a good way to do that yet. You'll have to inject a and reach into b to use it from within a behavior

@matthewtoast on Slack:

i would advise sticking to the flattened states for now

This is mostly a question of what API would be appropriate. We could:

1. do some magic in the build step to allow syntax like function(foo.bar.baz){}
2. adopt a convention like function(foo__bar__baz){} or function(foo$bar$baz){}
3. add meta info to behaviors with e.g. function(){}.triggeredBy('foo.bar.baz')

Or something else?
