Compiler: promises don't work well for nested operations

[josephjclark]

This doesn't work:

fn((state => {
   fn()(state).catch((error, state) => state)
})

The promise in the nested operation isn't compiled. so the catch isn't fed the state object

There could be two things at play here:

1. That extra function call in fn()(state).catch() is likely to be violating the compiler's expectations
2. I think promises are only compiled top level? We don't really have any business compiling code in a callback like this. We don't know if passing state is appropriate - usually it's not

Thinking about it I think the nested thing is super important. This is smelling like a won'tfix
