Span

final class Span(val coords: Long) extends AnyVal

A span indicates a range between a start offset and an end offset. Spans can be synthetic or source-derived. A source-derived span has in addition a point. The point lies somewhere between start and end. The point is roughly where the ^ would go if an error was diagnosed at that position. All quantities are encoded opaquely in a Long.
