Why is this an issue?

  Nested routines cannot be used as procedural values.


  This will normally cause a compilation error, but such errors can be bypassed by using the address
  of the nested routine with @.


  In this scenario, the code generated by compiler will have undefined behavior.

How to fix it
Do not use @ to get the address of a nested routine. If a method pointer is required,
convert the nested routine into a top-level routine.
