That would limit the lengths of the programs, but here the problem is
one of diversity and not length.  Without care eventually all the
programs in the population become degenerate versions of each other.

Indeed.  There's actually a mutation factor which I neglected to

Jupiter on the other hand is very much like MARS or Tierra in terms of
being on a circular memory space with processes having private registers
and stacks, rather than taking place on a two-dimensional grid.
