Cute idea!

However, one of the reasons I prefer exceptions to returning any sort of error object is because they act outside the normal return path.

The problem with "false == failure" is that it falls down as soon as you have "false" as a legal return value. For example, people often misuse read because it has different meanings for a false return value (0 == EOF, undef == error). People forget to check for the error condition - leading to nasty bugs.

The same sort of thing applies to any sort of "funny" return value - which in hindsight was why I was uncomfortable with the code I wrote in Test::Exception extension with (evil?) overloading :-)

With exceptions you don't have to worry about any confusion between legal return values and errors.

Another advantage of exceptions is that I can separate my error handling code from the error producing code, which makes things like massaging errors between different application tiers so much easier.

    [Corion]: Meh. I need to find myself a better "programming" feed than r/programming (which is just HackerNews reposts and advertisements, very little code). Maybe I should select a list of links that I liked on r/programming and then google for ...
    [Corion]: ... an aggregator site that also listed (ideally) all of these links once. And maybe also have an exclude list to blacklist some of the most spammy links that the site may have never mentioned at all
    [marto]: I gave up reading HN at all, and feel much better for it :P
    [Corion]: Now, how to best automate that Google search ... :-)
    [Corion]: marto: Yeah, I'm also short of not reading it at all. I already stopped reading it in the morning because it gave me a foul mood.
    [Corion]: The good posts on HN are the non-computing posts. Most of the other stuff is maybe relevant to you if you are 20 and live in Silicon Valley...
    [Corion]: Two attributes that don't describe me.
    [Corion]: Maybe I should also write a curator for HN or simply not read it anymore, like you do.
