This is exactly the problem I'm trying to avoid.  The problem is when
you call this millions of times you get millions of temporary objects.
 It's slow (lots of memory allocation) and causes garbage collector

Technically with that same approach it can look "proper":

   vertex_vector[20].x = 2.5

It's the same problem though with needing temporary objects.
