Help with sort: it does not seem to do anything.

I'm a bit confused, I have a very simple sort example, but it does not do anything at all. I must be doing something wrong, because I cannot image that I'm the first to touch this code. What is going on here? The following code gives as output:

mojo bug1.mojo
before: 0 13 76 46 53 22 4 68 68 94 38 52 83 3 5 53 67 0 38 6 42 69 59 93 85 53 9 66 42 70 91 76
after:  0 13 76 46 53 22 4 68 68 94 38 52 83 3 5 53 67 0 38 6 42 69 59 93 85 53 9 66 42 70 91 76


code: 
from random import random_ui64
from algorithm.sort import sort

fn main():
    alias size = 32

    var data_vec = DynamicVector[SIMD[DType.uint32, 1]](size)
    for i in range(size):
        data_vec[i] = random_ui64(0, 100).cast[DType.uint32]()

    print_no_newline("before: ")
    for i in range(size):
        print_no_newline(str(data_vec[i]) + " ")
    print("")

    sort[DType.uint32](data_vec) # inplace sorting does not seem to work

    print_no_newline("after:  ")
    for i in range(size):
        print_no_newline(str(data_vec[i]) + " ")
    print("")
