Issue Description:
When trying to add a try to a closure, the warning received is confusing if there is something within the closure which also needs a try. See attached screenshot for an example.
Per @jckarter, this is something which probably needs a clearer message: https://twitter.com/jckarter/status/969774890373996544
My personal suggestion for a message would be "try outside of a closure does not affect the code within the closure", but feel free to bikeshed that as much as you'd like.
