`vector-unfold``f``length``initial-seed``···`procedureThe fundamental vector constructor. Creates a vector whose length is

`length`and iterates across each index`k`between`0`and`length`, applying`f`at each iteration to the current index and current seeds, in that order, to receive`n + 1`values: first, the element to put in the`k`th slot of the new vector and`n`new seeds for the next iteration. It is an error for the number of seeds to vary between iterations.Examples:

(vector-unfold (λ (i x) (values x (- x 1))) 10 0) ;=> #(0 -1 -2 -3 -4 -5 -6 -7 -8 -9)

Construct a vector of the sequence of integers in the range [0,

`n`).(vector-unfold values n) ;=> #(0 1 2 ··· n-2 n-1)
