Data.Tuple.OneTuple
Description
OneTuple fills the tuple gap with a singleton tuple.
OneTuple does not support the usual parenthesized tuple syntax.
OneTuple
- has the expected laziness properties
- can be pattern-matched
- ships with instances for several standard type classes, including all those supported by H98-standard tuples
- requires no language extensions, except for hierarchical modules
