     To me, it also seems as if it would be a good idea, but using it
is awkward.  In some coursework, I used a Java cryptographic system.
It had a lot of exceptions to handle so my code had a lot of catches.
Because I did not know what was thrown, I wrote my code without them
and then added whatever the compiler stated was missing.  In those
catches, there really was not anything that I could do other than
reporting the error.

     I prefer reading the main flow of execution as a high-level
story.  Catches interrupt this.  When there are a lot of catches, they
make the main code harder to find.

     Thank you.
