Inspecting an implicit Exception when debugging inside a raise block

I'm using ruby-debug to dive into code that's throwing and silently eating exceptions. (The code is inside a gem, so I'm loathe to edit it directly without a really good reason.)

I get to this line:

   167        def catch_exceptions
   168          begin
   169            yield
   170          rescue Exception
=> 171            rollback
   172          end
   173        end
   174

As line 170 isn't defined as rescue Exception => e, there's no exception object declared.

Is there a way of inspecting this "implicit" exception object?

You can access the most recent exception using the global variable $!.

I know you don't always have a choice but consider fixing the gem or using a different one. That catch-all approach is really bad when it comes to tracing down exceptions.
