===============================

**Message emitted:**

Iterated list '%s' is being modified inside for loop body, consider iterating through a copy of it instead.

**Description:**

*Emitted when items are added or removed to a list being iterated through. Doing so can result in unexpected behaviour, that is why it is preferred to use a copy of the list.*
