Checked exceptions as in Java is in fact a horrible idea. If you assume
that the program is designed with error handling in mind from the start,
it could work, but in practice you will discover at some point that some
lowlevel error condition the highlevel need to handle. In that case 
all the methods in the entire call tree need to be changed. If the 
application is sufficiently large, you simply can't do that.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead. (from RFC 1925)
