Оно и понятно: функция `patientEmail` использует образец, который уже некорректен. Вот почему при использовании паттерн матчинга следует быть внимательным.

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.

«Голова» списка откусывается и игнорируется, а к `0` прибавляется `1`. Но поскольку результат сложения пока что никому не нужен, сложение не производится. Вместо этого, на второй итерации, мы видим следующее:

Как вы думаете, что произойдёт раньше? Применение оператора сложения или же применение функции `square`? Вопрос хитрый, ведь правильного ответа на него нет, поскольку существует две модели вычисления аргументов, а именно энергичная (англ. eager) и ленивая (англ. lazy).

Мы применили функцию `square` к аргументу `2`. Синтаксис предельно прост: имя функции и через пробел аргумент. Если аргументов более одного — просто дописываем их так же, через пробел. Например, функция `sum`, вычисляющая сумму двух своих целочисленных аргументов, применяется так:

А вот вычисленным не до конца называют такое выражение, которое начали было вычислять, но сделали это не до конца, то есть не до нормальной формы, а до так называемой «слабой головной формы» (англ.

И ещё. Возможно, вы слышали о так называемом «вызове» функции. В Haskell функции не вызывают. Понятие «вызов» функции пришло к нам из почтенного языка C. Там функции действительно вызывают (англ. call), потому что в C, в отличие от Haskell, понятие «функция» не имеет никакого отношения к математике. Там это подпрограмма, то есть обособленный кусочек программы, доступный по некоторому адресу в памяти. Если у вас есть опыт разработки на C-подобных языках — забудьте о подпрограмме. В Haskell функция — это функция в математическом смысле слова, поэтому её не вызывают, а применяют к чему-то.

Однако первый элемент списка так и остался невостребованным, поэтому выражение `2 / 6.054` по-прежнему остаётся лишь нашей мыслью, не более чем. В этом случае список `coeffs` всё равно остаётся в слабой головной форме, ведь внутри первого его элемента всё ещё вакуум.

Иногда space leak ошибочно путают с другой проблемой, называемой memory leak (англ. «утечка памяти»), однако это вовсе не одно и то же. Утечка памяти — это ошибка, характерная для языков с ручным управлением памятью, например, C. Если мы выделим память в куче (англ. heap), а затем потеряем указатель, связывающий нас с этой памятью — всё, выделенная память утекла, она потеряна для нас навеки. Но в случае space leak мы не теряем память: когда весь этот «хвост» из сложений в конце концов вычислится, память, занимаемая миллионами thunk-ов, освободится. Мы не теряем память, мы просто используем её слишком много.
