I swear I'm not trying to be inflamatory, but this is the _worst_ programming language feature I could ever imagine.

I swear I'm not trying to be inflamatory, but this is the _worst_ programming language feature I could ever imagine. I'm not trying to be hyperbolic, if I try to reason about it there is nothing I can come up with that I would dislike more in the realm of recent features that have been pitched in the PL community I was already in the camp that try/catch is "considered harmful", I dislike the concept of having a second, hidden, control flow that might get sprung up upon function callers, because it has side effects buried in the implementation of a callee that are not defined in the parameters or the returns, and I am not 100% sold on the benefits of "Things in the middle don’t need to concern themselves with error handling.", which I guess informs this opinion. Now since I hate that, I really, really would hate that on top of this, another programmer could write a hidden control flow upstairs that could, potentially, not just crash my code, but also do a lot of other things, such as coming up with default values for unexpected NULLs or whatever, which could THEN take something that would have crashed immediately, and turn it into something that crashes later down the line, away from the problem, with a varialble set to an inexplicable value that I have never put there myself What a nightmare to debug! I mean, come on
