I think Larry Wall is brilliant at deconstructing classic CS ideas. I think the deconstruction of classes in perl5 was really revealing to me (I was a C++ fan at that time).

Now he is deconstructing try-throw-catch.

I personally love exception handling. I find foo() or die() tiresome, but the alternative of not checking every return value is unthinkable.

You said "how they seem to move the core code further and further to the right". I interpret that to mean that the error handling (which I don't see as "core code") farther away form the code it is error checking or just a case of indent-itis. Both can be ameliorated by using more fine grained use of try-throw-catch. Using these blocks more often will limit nesting and keep error handling close to the code it handles.
