Why don't you install your fun? Filling the matrix with random values
is one of the most amusing aspects of life.
As I see in life.el, Luc already changed the life-pattern type from
defconst to defvar so it's good to install it now. But please rename
`random-life' to `life-random' to satisfy the package prefix. Thanks.
