Wow, the union literal optimization sounds massive, especially for type-level parsers like ArkType.
Previously, we'd avoid comparisons against character sets whenever possible due to the performance impact, but this should open the door to tons of new functionality, including making detailed regex validation and inference viable (shout-out to David Tai who recently implemented a type-safe regex parser and is working on adding similar functionality to ArkType :-)).
