  • Source: Model Driven Solutions ( Dr. Edward Willink)
  • Summary:

    The second example contains

    "if result then return;"

    which has a non-boolean condition expression and a missing endif.

    In the first example, it is not clear that the revisit adds rather than overwrites.

    In the third and fourth examples it is not clear why the second pass reuses the context for the first rather than creates new objects.

    Discussion

    The examples are much worse than suggested; verging on the diabolical.
