You do not have to worry about names interfering when you use local variables.
(ie: a dozen pistons can all use the same name for a variable, and no piston can see or act upon the variables stored in the other pistons)

On the other hand, if you use global variables, (ie: @globalVariable) then the names do have to be unique, since all pistons can refer to globals.
