If write physical formula with acceleration or length of the edge of square, human often use $a as variable. Sad about reservation of $a. I have a bad habit of using "a" from other languages.

    There is no better time than "now" to unlearn bad habits.


    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
