<p>Errors are a key component of writing software - programs, libraries, scripts, you name it. We need to check for

better.</p>

discussions about it), you can already see that there is one already mentioned major flaw in it - it operates just on a
single level: in functions. Now, one way to overcome this limitation is going full nuclear.
