I think part of the problem may be that non-trivial examples require 
rather a lot of context. An example that comes to my mind is if an 
application is combining a bunch of different libraries, and calling 
them all in sequence:

try
{
$fooService->doStuff($data);
$barService->doMoreStuff($data);
$bazService->doDifferentStuff($data);
}
catch ( FooException | BarException | BazException $e )
{
// We don't care which library threw the exception, the action is always 
the same
throw new AppException($e); // Hide which libraries we're using to 
implement the function
}
