Fun Fact: Rust didn’t always support leading pipes (which are optional), not even at v1.

Unless I’m hallucinating memories, the support was added with influence from Haskell.

Neither the person who contacted you was a real user of that instance, nor their “concern” was legitimate.

Congrats. You got successfully manipulated. And opened yourself up for further future manipulations.
