 * Revert "Speed up input mapping lookup by avoiding rescuing exceptions" from v5.3.0, it caused a regression on dev/test environments with custom inputs.
 * Try a slightly different approach to input lookups, without relying on regexp, to see if that helps with performance as originally intended.
 * Add support to Ruby 3.3. (no changes required.)
