Today I saw the topic. sum-even-numbers-1-100 At that time, it was already closed but not the point. Other thoughts came to mind.
All newcomers to Haskell are afraid that when they study it, their brains will turn inside out. I did not notice anything like that. And all because the brains of all Unicsoids are initially in the correct position. Let's look at an example concerning this theme.
On Haskell you need to write one line.
But analogue on bash

seq
SEQ(1) User Commands SEQ(1)NAME
seq - print a sequence of numbers
SYNOPSIS
seq [OPTION]... LAST
seq [OPTION]... FIRST LAST
seq [OPTION]... FIRST INCREMENT LAST
DESCRIPTION
Print numbers from FIRST to LAST, in steps of INCREMENT.
Mandatory arguments to long options are mandatory for short options too.
-f, --format=FORMAT
use printf style floating-point FORMAT
-s, --separator=STRING
use STRING to separate numbers (default:
)
-w, --equal-width
equalize width by padding with leading zeroes
--help display this help and exit
--version
output version information and exit
If FIRST or INCREMENT is omitted, it defaults to 1. That is, an omitted INCREMENT defaults to 1 even when LAST is smaller than FIRST. The
sequence of numbers ends when the sum of the current number and INCREMENT would become greater than LAST. FIRST, INCREMENT, and LAST are
interpreted as floating point values. INCREMENT is usually positive if FIRST is smaller than LAST, and INCREMENT is usually negative if
FIRST is greater than LAST. FORMAT must be suitable for printing one argument of type 'double'; it defaults to %.PRECf if FIRST, INCRE-
MENT, and LAST are all fixed point decimal numbers with maximum precision PREC, and to %g otherwise.
