Number theory: primes, arithmetic functions, modular computations, special sequences

Modular arithmetic, promoting moduli to the type level

Command-line tool to list Hackage reverse dependencies

Infinite lists aka streams

Fast polynomial arithmetic in Haskell (dense and sparse, univariate and multivariate, usual and Laurent)

Integer roots and perfect powers of arbitrary precision

Bit vectors: 8x less memory, up to 3500x faster than Vector Bool

Divide without division

Test your Haskell code by exhaustively checking its properties

Extend Cabal build-depends from the command line

Compatibility layer for Data.Array.Byte from base

Lazy infinite compact streams with cache-friendly O(1) indexing and applications for memoization

Split integers into digits, blazingly fast

Linear programming over exponent pairs

Benchmark a given function for variable input sizes and find out its time complexity
