Various small helper functions for Lists, Maybes, Tuples, Functions. Some of these functions are improved implementations of standard functions. They have the same name as their standard counterparts. Others are equivalent to functions from the base package, but if you import them from this utility package then you can write code that runs on older GHC versions or other compilers like Hugs and JHC.

All modules are plain Haskell 98. The package depends exclusively on the base package and only that portions of base that are simple to port. Thus you do not risk a dependency avalanche by importing it. However, further splitting the base package might invalidate this statement.
