[COFF] [TUHS] Re: Conditions, AKA exceptions. (Was: I can't drive 55: "GOTO considered harmful" 55th anniversary)

[Marshall Conover]

While all this error and exception discussion is going down, I have to
mention this piece: http://joeduffyblog.com/2016/02/07/the-error-model/

The author worked at MS on their "midori" research OS, and discussed what
went into their decisions around using return codes, exceptions, etc. I
felt it was a nice breakdown of the pros and cons of the different
approaches, and fleshed out the concepts in my mind a bit. I thought others
might enjoy it as well.

That said, I absolutely loathe exceptions with all my heart. In my
experience, along Warner and Matt's lines, they're more prone to the sort
of abuse that wastes my time than they are productive. It's not that they
can't be used well, they just so often aren't.

Cheers,

Marshall
