What "performance degradation" do you mean? I thought we were commenting on the degradation of code readability by the use of "magic numbers" instead of symbolic constants?

In an if-chain you have to use variables, how would you use constants without a variable to compare it to? What different kinds of variables do you mean?

I guess I do not understand what you mean by your above comments, sorry. :(
