    I did some user testing with Python 3.8 and found that math.dist() was a little restrictive in only accepting coordinates as tuples. Mostly it worked out fine except but was a little inconvenient with generalized unpacking:

    label, *coordinates = cursor.fetchone() # coordinates is a list

    Also, it would be nice to allow numpy arrays as arguments.
