You misunderstood me.

If there are multiple functions or classes in a file, when I change
variables in a function/class, I have to make sure that they are not
in other functions or classes. This makes the refactoring process
tedious. If I have a single class/function in a file, I can safely
change variable names without worrying broken other classes or
functions.
