When I was a callow young programmer learning the ropes and enjoying the sheer power of the C language, I got a bit carried away with the macro pre-processor’s ability to let you redefine the language.
As much fun as that is, and as much as it can make your source code look cool, it’s a really bad idea. At some point the folks in comp.lang.c read me the riot act about it, and they were right.

Along with “always use less-than” is another great piece of always advice, except this one is a prohibition, a never rather than an always (same thing, really, from a programmer’s point of view).
It has to do with never having literal values embedded in your code!
