Sigils, the non-alphabetic prefix characters used in programming languages, have a bad reputation among some programmers who view them as old-fashioned or pointless. However, Hacker Noon argues that sigils are a powerful tool for writing clear and expressive code. To support this argument, the article explores non-programming situations where sigils aid clarity, such as chat messages and email labels.

In general, using sigils can help communicate more clearly and reduce cognitive load.
