I'm just a hobbyist but...are you guys using exceptions like they're conditional statements?? I thought those were for only when shit is seriously wrong and execution can't continue in the current state. Like if some resource was in a bad state or some input was malformed.

Or maybe I haven't worked on anything complex enough, I dunno.

You don't want to use exceptions in normal control flow, because they're extremely slow. Every time you throw an exception, it has to collect a stacktrace, which is hundreds, if not thousands, of calculations, compared to a handful of calculations for returning a boolean or an enum variant.
