I think it is fair to say that it
depends on how you specify a piece of
code. What should it do? under which
conditions should it fail or exit
abnormally? etc. IMO thorough
pre-validation of input data is
preferrable to relying entirely on the
occurrence of an exception. This is
because, it is possible that the
function you call can return incorrect
results without any exceptions raised
(or other error information) if you feed
it unchecked input data... and that
depends on how the lower level function
is specified, implemented and tested.
