Implement a fast hash-based lookup for the In function, similar to the fast lookups already available in Recode/Categorize. Should be enabled only when the reference values are static and can all be matched to a single type.
Since there is a small possibility of behavioral differences, a system variable kill switch is going to be added to disable the fast lookup.
