## Examples

- The new feature added over five hundred LOC to the project.
- The lead developer argued that reducing the total LOC would make the software easier to maintain in the long run.
- While LOC is a common metric for productivity, many engineers argue it is a poor indicator of quality since more code does not necessarily equate to better functionality.

## Usage notes
