They are only special in special cases. Outside of that, they are as
friendly as your other variable.

People who pipe up upon seeing some code that uses $a and $b for
illustrative purposes, predicting hell and doom even if there's no sort
in that code behave like mindless grasshoppers, incapable of thinking for
themselves. They probably also argue one shouldn't take water with you
in a desert, because more people drown in water than in any other liquid.
