From one point of view, yes.

Another point of view is that it's a new kind of de-encapsulation.

Apparently this is a 'global' variable:

    int variable = 0;
    void foo() {
      variable++;
    }
    void bar() {
      variable++;
    }

but this is an 'encapsulated' variable:

  class MyClass {

    int variable = 0;
    void foo() {
      variable++;
    }
    void bar() {
      variable++;
    }

  }

You can block the top one in a code-review because "global variable", and tell the developer to fix it by passing the variable in and out of functions when needed, but I have a feeling the bottom one's getting merged even if you object on the same grounds.

The Common Lisp Object System disagrees with functions being attached to data.
