| 23 | When a string is transformed into a range of | ||
| 24 | params, the empty string becomes ambiguous: | ||
| 25 | it can be an empty range, or a range with | ||
| 26 | one param. The value `not_empty` is used on | ||
| 27 | construction to inform the transformation | ||
| 28 | that the empty string should be treated as | ||
| 29 | a one-element range. This simplifies | ||
