They are not "completely different".  Think about the following C
code:

  int foo() {
    int a
    a = 42;
    printf("a=%d\n", a);
    {
      int a;
      a = 55
      printf("a=%d\n", a);
    }
    printf("a=%d again\n", a);
  }

This is somewhat confusing but completely valid code in C.  Besides,
in (future) Ruby, you will be warned for a bad style.
