I didn’t think I was going to like it but I really do. My only concern,
which isn’t really a deal breaker, is what it would look like to chain multiple
try and let statement in the same guard. Unless that scenario works well I
don’t think you could convince others. i.e. In the case where I have:
guard try something(), let thing = optionalThing catch { }
What happens when the let fails? No implicit error?
