Local variable is reassigned in closure or anonymous class

Reports local variables assigned to expression with different type inside of closure or anonymous class.

Example:

  int sum = 0
  [1, 2, 3].each { sum += 'as' }
  println(sum)

As a result, the integer variable sum is reassigned to a String expression.
