This leads to three ways to emit a source-line in this function:
 * `recordSourceLine`,
 * `RecordSourceLine` (a helper lambda around the former,)
 * `recordTargetSourceLine

Which has the potential to be confusing -- would it be alright to always call `recordTargetSourceLine` from the helper lambda perhaps, just to reduce the number of options?
