 Slice mutations to swap lower/upper values, or change range e.g. :code:`x[2:] to x[:2]`

+The "ToZero" operations
 change the list by moving the upper bound by one unit towards zero from the absolute value and
 then applying the original sign e.g. :code:`x[0:2]` would become :code:`x[0:1]`, and
 :code:`x[-4:-1]` would become :code:`x[-4:0]`. In the positive case, which is assumed to be the

+operations appear self-referential in the report output. This is because an operation identified
