As a soon to be senior citizen, I would like to put in my 2 cents worth on the suggested naming convention for aliases. Being an over 40 developer with less than perfect eye sight, I find it much easier to distinguish between alias like a, b, or c than it is Mnemonic aliases like clo and clc. The similarities between aliases like clo and clc are some times distracting and easy to confuse. Plus it adds addition characters to the statements, which adds to the statement's length. I suppose the idea of readable code would depend on the eyes of the beholder.
