The recent Quick Reference posting reminded me I had never announced
this to the beginners list - my apologies.
I've created a "cheat sheet" for Haskell. It's a PDF that tries to
summarize Haskell 98's syntax, keywords and other language elements.
It's currently available on my blog and hackage. Once
downloaded, unpack the archive and you'll see the PDF. A literate
source file is also included.
If you install with "cabal install cheatsheet", run "cheatsheet"
afterwards and the program will tell you where the PDF is located.
I wrote this for beginning to intermediate Haskell programmers. I
found it difficult to look up some of the less-used syntax and other
language stumbling blocks as I learned Haskell over the last few
years, so I hope this document can help others in the future. With
that in mind, I welcome your comments or patches.
