The premise of basic-prelude is that there are a lot of very commonly desired
features missing from the standard Prelude, such as commonly used operators
(<$> and >=>, for instance) and imports for common datatypes (e.g.,
ByteString and Vector). At the same time, there are lots of other
components which are more debatable, such as providing polymorphic versions of
common functions.
So basic-prelude is intended to give a common foundation for a number of
alternate preludes. The package provides two modules: CorePrelude provides
the common ground for other preludes to build on top of, while BasicPrelude
exports CorePrelude together with commonly used list functions to provide a
drop-in replacement for the standard Prelude.
Users wishing to have an improved Prelude can use BasicPrelude. Developers
wishing to create a new prelude should use CorePrelude.
