Is This a Better Diagnostics?

In the wild, and when you're developing diagnostics like this, all of the test cases that you write are going to make sense. But then in the wild in a big production code base, maybe there's some some some complex case where somebody gets this diagnostic and they're like, I don't like what which variable are you referring to? Like it doesn't cost anything for the diagnostic to explicitly say like, hey, this is the thing. This is the name of the thing that that I'm talking about. That's a better diagnostics to me. It like it talks about what it's subject is."
