Answer 1

Its not just related to scala. In most languages you can do that. Because as you said the variables are in different scope.

In c#

class test
{
      int i;
      void method(int i)
      {
          this.i = i;
      }
}

this represents the self type. I am not sure about the this functionality in scala. But the reason for your question is scope level.
