I understand your perpective, but IMO there's 2 broad categories,
system exceptions, and then those things that the user of the library
does wrong, for example NumberFormatException in Java. The exception in
my library would be almost identical to a NumberFormatException.

Also, it may not be the programmer, but the end user that made the
mistake. For example, typing 5.5 in a field that only accepts
integers.

the user could validate it before making the object, but then again,
that could be part of the object's job.
