alt Hacker NewsYes, I've never quite understood the "But with exceptions it's hard to debug why the error occurred after the fact, its better to be explicit in advance" - The stack trace points exactly to the line. And usually, with the error message and context, its all I need. Maybe I'm missing something that someone can inform me.
Yeah, this kinda becomes a problem when the library you are using does not distribute its source code, so even if you get the line, this information is practically useless to you.
This has been my biggest problem with exceptions, one, for the reason outlined above, plus it's for how much time you actually end up spending on figuring out what the exception for a certain situation is. "Oh you're making a database insertion, what's the error that's thrown if you get a constraint violation, I might want to handle that". And then it's all an adventure, because there's no way to know in advance. If the docs are good it's in the docs, otherwise "just try it" seems to be the way to do it.
