Nit: Instead of putting this new parser/printer pair in the "Parsers/Printers for operations including clauses that define entry block arguments" sections of the file, create a new section to keep both functions together, as it's done for other custom clause printers/parsers.

// Parser and printer for in_reduction Clause
