Suspicious variable/parameter name combination

Reports an assignment or a function call where the name of the target variable or the function parameter does not match the name of the value assigned to it.

Example:

  var x = 0;
  var y = x;

  var x = 0, y = 0;
  var rc = new Rectangle(y, x, 20, 20);

Here the inspection guesses that x and y are mixed up.
