The man page is correct.  However, you have to define the function before
you declare it static. Thus,
[snip]
                # Static method
                function totalpop {
                        printf 'Total population is currently %d.\n' "${_.polation}"
		}
                typeset -fS totalpop
[snip]
should work.
