Sorry, I don't buy this argument for a second. Programmers need to do there job, not ignore
it for the 'time being' as lazy developers will definately do otherwise. Perhaps you can get

nothing should throw checked Exception is foolish.

+After this, take a careful look at Cocoon's code base and count how many exceptions are swallowed
or rethrown as unrelated kind of exceptions (with the ensuing mile-long stacktraces). It's
not that checked exceptions are bad in theory. It's that in practice very few developers deal
with them sensibly.
