Relatedly, the core team discussed changing #setline to follow camel case as well. As was brought up on another thread, the syntax for #setline is inconsistent with the other # directives because it doesn’t use parentheses. The core team discussed this a bit and recommends resyntaxing #setline to:
#sourceLocation(file: "foo", line: 42)
