@mcc I'll keep this in mind. I'm going to run a bisect to see if I can get to the point of no return.

That said, I _do_ remember upgrading Rust - if that's affecting this, that feels like compiler bug space, no?

@jalcine The code worked before and doesn't now? That's interesting if so, I don't know but I *assume* that violates the forward compat promises the Rust team makes. I think (?) backcompat breaks are only supposed to happen with new Editions.

You may already know this but I think Rustup will let you if you want to double check whether that's the case
