REMOVE_ITEM

Description
Removes the first item from a list that matches the given criteria. Returns a list all other items except the matching one, in their corresponding order.
The criteria is defined as a formula at the second parameter. The formula is evaluated with each item in the list until a matching item is found. The formula must result in a true/false value. If true, then item will be excluded from the result, otherwise it will be included. Note that only first matching item is removed; if multiple items matches the criteria, then only first one is removed. If no matching item is found, then the original list is returned unchanged.
