Haiku

Haskell haikus

1st prize in Original code poems in the "Waikato ACM Code Poetry Contest 2006":

Haskell is concise Functional well-typed and neat It is like Haiku

By FMota, preserved in Lambdabot:

Haskell's cryptic form is natural to some folks and so is Haiku's

Monad haikus

From Monad laws - Is that really an "associative law"?:

Monad axioms: Kleisli composition forms a category.

From #haskell

empty list error: this elegant program dies so very quickly

less time debugging more time downloading your brain to the type system

type checker: "You fool! What you request makes no sense - rethink your bad code."

Incarnation of fmap abstract abstraction Haskell semantics

GHC compiles lambdas are being lifted the wind is dying

By shapr:

the snow falls slowly the lambdas are lifting - weak head normal form.

By blackh:

Haskell programs are viewed in terms of "data flow"; All state is transient.

From haskell-cafe

By Thomas Hartman:

You come for magic silver bullets slaying bugs... It is only code!

By Neil Davies:

Yesterday it worked. Today it is still working Haskell is like that!

By Pekka Karjalainen:

Without a kigo or requisite syllables, haiku don't typecheck

By Niklas Broberg:

Trapped in a monad, use unsafePerformIO! Purity tainted...

By Heinrich Apfelmus:

drop autumn leaves until . all . pure . color . Left fail . frost otherwise

By Richard O'Keefe[1][2]:

Soft rain falls while Haskell infers all my types.

In my room    Haskell humbles me; Look, green leaves!

December buds swell. Categories unlimit Haskell I once knew.

From The Monad.Reader

See Issue 9 of The Monad.Reader; these haikus by Wouter Swierstra all related to Summer of Code projects:

Abstracting Parsec over any input type. The world on a String.

Improving Hackage. Daemons can build your package and Haddock your code.

Haskell IDE, will it ever beat Emacs? Only time will tell.

To load code faster and save disk space, GHC must share libraries.

Binding to libcurl. Get your data from the web. Who needs Firefox?

A tracer that can't cope with Cabalized code is an old Hat, indeed.
