[swift-evolution] [Pitch] Introducing #fileName debug identifier

[Radosław Pietruszewski]

Agreed. It’s really not useful for anyone to see `/Users/radex/Documents/Projects/MillionDollarAppIdea/` when logging errors or… anything really.

I think a project-relative path should just be the new #file. I’m not even sure the full absolute path is necessary — but if it is, I’d rename it.
