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.
