regaurdless that's all meaning less in the scope of programming in programming constants exsist all that is required is the proper declaration. What it sounds like to me is that you want a variable with it's scope being limited to a script. kind of like in C were the variable isn't declared ext. so other included files will not be able to manipulate said variable. (not counting indirection). I could see this type of variable as being advantadges to the plugin coders. However in no way would I even imply that a variable with such scope would perhaps be a constant. A constant implies a value that cannot be changed and inwhich is completely global.
