This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
String is removed in favor of lazy Data.Text.Lazy.Text.
No more Num
The Num typeclass is now just for types which can be converted from
integer literals.
Semigroups
Semigroups are now in scope by default, as well as some useful
wrappers.
Semirings
A Semiring has the operations + and *, and the members one
and zero. Bool is a Semiring, as is Integer, etc. Num is
not a superclass of Semiring.
Sensibly strict
Several functions, such as foldl, sum, product, etc. are strict
as default.
No unnecessary Monads
Functions such as Control.Monad.sequence, Control.Monad.>>, and
Control.Monad.replicateM are removed in favor of the equivalent
sequenceA, *>, and replicateA on Applicatives.
Fewer partial functions
Functions like head, last, minimum, etc. now return Nothing
when called on empty structures. tail and init return empty
lists when called on empty lists.
Data structures
Map and Set (the strict variants) are now in scope by default,
with a minimal, non-colliding aliased api.
Transformers
State is now in scope by default.
Debugging
Handy functions like trace, traceShow, and notImplemented are
in scope by default. They give warnings when used so they can't be
forgotten.
Other handy functions
An O(n*log n)nub, foldr2, converge, bool, and others.
