Quoting from the style guide:

	Declaring variables as '[static] const' gives variables an actual type and
	makes the compiler do type checking for you; the preprocessor does _no_
	type checking whatsoever, making it much more error prone. Declaring
	variables with '[static] const' also makes debugging programs much easier
	since the value of the variable can be easily queried and displayed.
