"""Remove all items from a list that are in the items_to_remove set.

|
|
This method optimizes for the common case of removing a single item,

falling back to list comprehension for multiple items.

Args:
|
|
lst: The list to remove items from
|
|
items_to_remove: Set of items to remove
|
|
|
|
Returns:
|
|
Either the modified original list (for single item removal) or
|
|
a new list (for multiple item removal). Callers should use the
|
|
returned value.
|
|
|
|
Note:
|
|
For single item removal, this modifies the original list in-place
|
|
and returns it. For multiple items, it creates and returns a new list.
