dict_add_elem(dictionary, key, element)This function returns the result of adding element to the list value key in dictionary. If dictionary has no association with key key, then
dict_add_elem() adds an
association [key, [element]] to dictionary. If
dictionary has an association with key key, and the value
part of the association is a list, then dict_add_elem() adds
element to the end of that list. If dictionary has an
association with key key, but the value part of the association is
not a list, then dict_add_elem() throws a ~type error.
Examples:
dict_add_elem(#[["foo", ["bar"]]], "foo", "baz")
=> #[["foo", ["bar", "baz"]]]
dict_add_elem(#[], "foo", "bar")
=> #[["foo", ["bar"]]]
