And you know what? In my experience it's not less robust. So my code hasn't had every possible failure case thought through and explicitly handled in advance.

And you know what? In my experience it's not less robust. So my code hasn't had every possible failure case thought through and explicitly handled in advance. That's good. Firstly some of those errors are so rare they'll almost certainly never occur in my program's lifetime; by not having to handle them explicitly and individually I save time and money. Secondly I can guarantee that, no matter how good I think I am, the program will eventually find a way of crashing I'd not considered; this approach gives me a clean means of handling unforeseen errors as well. A bad programmer can write bad code in any pattern and with any tools. A bad C programmer using return values can create so many different standards for how to handle errors that you might as well get out the divining rods to read the code. Personally, done right (as with anything) I happen to like try...catch.
