not in this case. i fixed it.
the symbols are object for very specific reason and i don't need such a general case comparison. They will be integer, or string, or in one case a very custom type that is only handled in one scenario.
it's weird, but the algorithm behind it is such that the weirdness is unavoidable.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

That's a hacky way to do a sum type and the OO Police would like to know your location.

LOL. It's not a sum type.
It's ... hard to explain. It has to do with LALR and LL table generation, and the mechanics behind it.
I represent a CFG using a series of arbitrary symbols ids.
Users will probably only plug strings in here, but behind the scenes this CFG needs to be able to hold ints, and a special augmented symbol identifier <first#>ID<follows#>
However, as long as the user doesn't demand the impossible of the CFG they aren't limited to strings.
All that's required is an object to have identity equality semantics or at least be consistent in terms of refs it passes around and for the object to be able to get a hashcode off of it.
So object is okay here. There are caveats, but honestly, it was C#'s string optimization + a bug in my code that was causing me headaches. It all works fine now.
This is a *very* rare and very specific corner case for a very ugly/convoluted series of algorithms used to generate parsers.
So some rules will be bent. Others will be folded, spindled and otherwise mutilated.
So far I've never seen one even "readable" implementation of these algorithms, but mine is coming close.

i feel like my code would have, if it had an HR department. Glad I didn't implement that.

Yeah, I was the smartest kid in my social group, but I was/am a loner.Figure that.
It always amazed me that ((/3)*3) != 1 on a finite precision machine and we could still actually do useful calculations.

lol. yeah i guess. if debugging is interesting and challenging. I fixed it though so yay.
I had an == in a couple of places where I meant Equals - yes it was that simple, as the trickiest bugs often are.

Or in java, if you have the same class loaded by 2 different class loaders!
You also end up with multiple instances of statics, etc.
which means
One singleton per class loader...

That's weird. I always side eye java for some of its dark corners - they type system is dodgy, IMO.

I should add- I blame myself for the problem. I can clearly explain and understand why this problem occurred. It even makes sense, once you understand the twists and turns involved. It's not due to a hack, or a weird type system. It's due to the fact that object - the root type in the heirarchy - has no == overload associated - because it wouldn't make sense with it so == will only do reference comparisons, just like C++ on an object.

I've never watched an episode - but I suspected it might have been involved, since it was broadcast yesterday.

I just made a post in the reddit rust section, with my honest critique of the language from the perspective of an experienced C++ developer who has been exploring it. There were a good many responses and a good discussion going on. But presumably it wasn't sufficiently positive, and it just got whacked.
I never cease to be amazed at how language fans circle the wagons against any criticism. For a minute there I thought the Rust section might be actually more mature than the C++ one, where punitive down-voting is rampant. But I guess not.
That doesn't fill me with an urge to commit to the language.

Me: Product X shouldn't _____ .
Fan: But it does.
Me: Yes, but it shouldn't.
Fan: Of course it should; that's how it was designed.
Me: But it shouldn't have been.
Fan: It's the paradigm the designer chose.
Me: It was a poor choice.
Etc. etc. etc.
It's been going on for decades and it won't change.

In this case, Rust is still fairly young and has room for for growth. I was just throwing in my two cents on what I felt was holding me back from committing to it. If people don't speak up, no one's going to guess what we want.

Sure, but if the designer/implementer doesn't ask for input (when it will actually help) it's hardly any use (after the fact).
As with complaining about some of the features of C.
When Walter Bright was designing D (twenty years ago now?), he did ask for input on certain features, and took the feedback of testers into consideration.
Yet which language is getting more traction?
