I'm submitting a separate update to the accepted setline proposal. It does not seem to fit into the 0039 write-up. The pull request for 0039 is
I'm confused about setline. Will it be `setLine` or `sourceLocation`?
Accepted form and Modified design
After discussing how to rationalize naming and capitalization of identifiers in the “#” namespace, the core Swift team has adopted a lower camel case <https://en.wikipedia.org/wiki/CamelCase> model for identifiers.
The accepted form will use lower camel case either as #setLine or #sourceLocation.
The syntax for #setLine/#sourceLocation is inconsistent with the other # directives in that it doesn’t use parentheses. After discussion, the core team will adjust the call to use parentheses and comma-separated colon-delimited argument and value pairs.
The final syntax will be either
#setLine(file: "foo", line: 42) // or
#sourceLocation(file: "foo", line: 42)
Please let me know and I'll modify and submit a PR

>> - The community and core team uniformly agree that this proposal increases uniformity in the swift language.
>> - We discussed how to rationalize naming and capitalization of identifiers in the “#” namespace and prefer to move to a model where it uses lower camel case.
>> - The argument label on imageLiteral should be “resourceName” to describe the role of the string and avoid needless words, following the naming guidelines from SE-0006.
>> As such, the preferred spelling of these literals are:
>> #colorLiteral(red: 0, green: 0, blue: 0, alpha: 0)
>> #imageLiteral(resourceName: “foo")
>> #fileLiteral(resourceName: “bar”)
> 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)
