  • Coding sizes symbolically instead of literally can provide two benefits: 1) A well chosen symbol documents, or at least suggests, the reason for the choice; and 2) when other parts of the program or module need to be tailored to that choice, an expression using the same symbol can make that automatic, making maintenance much easier.

  • [A bit off topic, but] "user" is ambiguous as it can mean one of a number of people. It usually implies the end user, the consumer of final product, if not stated otherwise. It could be the next programmer, the immediately next consumer of your code, who might, in fact, be you (typical, in my own experience) a year or more after I've forgotten the nitty-gritty internal details of it). Or a system designer who includes your code as a ready-to-go module in his/her product. I suspect you meant the second "user". Commented May 20, 2015 at 17:39
