Example

Add to a list.

The add verb appends one item to an existing list while keeping the list's type rules intact.

Copyremember a list called scores with 10 and 20
add 30 to scores
show scores

Output:

Copy10, 20, 30

add is silent when it succeeds. If the target is not a list, the item has the wrong type, or an each loop tries to mutate the list it is walking, Liminate returns an error instead of guessing.
