Вовсе нет. История Haskell началась ещё в 1987 году. Этот язык был рождён в математических кругах, когда группа людей решила создать лучший функциональный язык программирования. В 1990 году вышла первая версия языка, названного в честь известного американского математика [Хаскелла Карри](https://en.wikipedia.org/wiki/Haskell_Curry). В 1998 году язык был стандартизован, а начиная с 2000-х началось его медленное вхождение в мир практического программирования. За эти годы язык совершенствовался, и вот в 2010 мир увидел его обновлённый стандарт. Так что мы имеем дело с языком, который старше Java.- Read upRead up

MD013 - Line length
Tags: line_length
Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)
This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks and/or tables parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

Haskell создавался многими людьми. Наиболее известная реализация языка нашла своё воплощение в компиляторе GHC (The Glasgow Haskell Compiler), родившегося в 1989 году в Университете Глазго. У компилятора было несколько главных разработчиков, из которых наиболее известны двое, [Simon Peyton Jones](http://research.microsoft.com/en-us/people/simonpj/) и [Simon Marlow](http://community.haskell.org/~simonmar/). Впоследствии весомый вклад в разработку GHC внесли ещё несколько сотен человек. Исходный код компилятора GHC [открыт](https://ghc.haskell.org/trac/ghc). Кстати, сам компилятор на 82% написан на Haskell.- Read upRead up

Parameters: punctuation (string; default ".,;:!?")
This rule is triggered on any header that has a punctuation character as the last character in the line:
# This is a header.To fix this, remove any trailing punctuation:
# This is a headerNote: The punctuation parameter can be used to specify what characters class
as punctuation at the end of the header. For example, you can set it to
'.,;:!' to allow headers with question marks in them, such as might be used
in an FAQ.

Сравнение Haskell с другими языками выходит за рамки этой книги. Несколько раз вы встретите здесь кусочки кода на других языках, но я привожу их исключительно для того, чтобы подчеркнуть различие с Haskell, а вовсе не для сравнения в контексте «лучше/хуже». И вообще, я буду изо всех сил стараться не восхвалять Haskell без меры, я хочу лишь рассказать вам правду о нём. Мой вывод об этом языке я уже сделал, а свой вывод о нём вы должны сделать сами.- Read upRead up

И да и нет. Освоение Haskell сложно в первую очередь из-за его непохожести на остальные языки, поэтому людям, имеющим опыт работы с другими языками, мозги поломать придётся. Именно поломать, а не просто пошевелить ими: Haskell заставляет иначе взглянуть даже на привычные вещи. С другой стороны, Haskell проще многих известных языков. Не верьте мне на слово, вскоре вы и сами в этом убедитесь. И знайте: многие люди, узнав вкус Haskell, категорически не желают возвращаться к другим языкам. Я вас предупредил.- Read upRead up

Haskell — чисто функциональный язык программирования общего назначения, может быть использован для решения самого широкого круга задач. Компилируемый, но может вести себя и как скриптовый. Кроссплатформенный. Ленивый, со строгой статической типизацией. И он не похож на другие языки. Совсем.- Read upRead up
