Haskell is a language that embraces Unicode, allowing developers to use certain Unicode symbols in place of their corresponding keywords. With the UnicodeSyntax extension enabled, developers can use symbols like ∀ instead of for, making their code more elegant and readable.

In this article, the author explains how to use digraphs in Vim to easily write Haskell programs with Unicode symbols. The article provides an example of defining the predicate ∈ on lists as an alias for elem using the Unicode symbol. The article also includes a mostly comprehensive list of keywords that have Unicode alternatives, which can be found in the GHC user’s guide UnicodeSyntax extension page.

By combining Vim's digraphs feature and Haskell's UnicodeSyntax extension, developers can write beautiful Haskell programs with ease. The article provides a short write-up on how to use these features to make Haskell code more elegant and readable.

Overall, this article is a great resource for developers who want to write Haskell programs with Unicode symbols. By using digraphs in Vim and the UnicodeSyntax extension in Haskell, developers can create more beautiful and readable code.
