Many tried to teach us how to write code less dreadful, be it implicitly as
B. W. Kernighan and D. M. Ritchie in The C Programming Language did,
be it explicitly as
R.C. Martin in Clean Code: A Handbook of Agile Software Craftsmanship
did.So we should check our code for files too long or wide, functions with too
many lines, too wide lines, too many arguments or too many levels of nesting.
