Assignments to 'for' loop or 'with' statement parameter

Reports the cases when you rewrite a loop variable with an inner loop.

Example:

    for i in range(5):
      for i in range(20, 25):
          print("Inner", i)
      print("Outer", i)
  

It also warns you if a variable declared in the with statement is redeclared inside the statement body:

    with open("file") as f:
      f.read()
      with open("file") as f:
