This module implements infinite arrays. *

make default_size x creates an infinite array, where every slot contains x. The parameter default_size represents the initial physical size of the underlying array. It must be nonzero. *

get a i returns the element contained at offset i in the array a. Slots are numbered 0 and up. *

set a i x sets the element contained at offset i in the array a to x. Slots are numbered 0 and up. *
