Detailed Description

This class represents the benefit of a pattern match in a unitless scheme that ranges from 0 (very little benefit) to 65K.

The most common unit to use here is the "number of operations matched" by the pattern.

This also has a sentinel representation that can be used for patterns that fail to match.
