Lists

list (a1, a2, ...) Built-in Function
Create a new list with elements given by the arguments a1, a2, ....

nth (list, n) Built-in Function
Return the n-th element of list.

append (list, a1, a2, ...) Built-in Function
Return a new list created by appending a1, a1, ..., to list. If any of the arguments to be appended is a list, its elements are appended individually. For example,
x = list (1, 2);
y = list (3, 4);
append (x, y);

results in the list containing the four elements (1 2 3 4), not a list containing the three elements (1 2 (3 4)).

reverse (list) Built-in Function
Return a new list created by reversing the elements of list.

splice (list_1, offset, length, list_2) Built-in Function
Replace length elements of list_1 beginning at offset with the contents of list_2 (if any). If length is omitted, all elements from offset to the end of list_1 are replaced. As a special case, if offset is one greater than the length of list_1 and length is 0, splice is equivalent to append (list_1, list_2).

islist (x) Built-in Function
Return nonzero if x is a list.
