Seriously? Mainstream languages are busy adding tuples because they make code so much cleaner when used appropriately. Leaving them out of Simple Haskell™ would be a big mistake, IMHO.
Yes this appears to be a silly suggestion, tuples are everywhere, especially as arguments for functions where it does not make sense to name the fields. They are also a structural type and records in Haskell are, unfortunately, nominal types.
If Haskell records were structural (one would use newtype to make a nominal record), then tuples could be syntactic sugar for a structural record with field names 1, 2 etc. There is value in unifying them with records, but we still need them.
