Subject: arrays without brackets?

I suspect I'm overlooking something in the documentation. If so, please point
me in the right direction.
My understanding of arrays is based on the reference manual "2.7.4 Arrays in
CFEngine 3". The defining characteristic of the syntax seems to be square
brackets:
---------
vars:
"array" string => "value1";
"array" string => "value2";
#etc.
"indices" slist => getindices("array");
---------
Fine. But over the months, and particularly in a forum thread here today, I
seem to have seen another possibility:
--------
vars:
"sysctl" string => "net.ipv4.ip_forward = 0";
"sysctl" string => "net.ipv4.conf.default.rp_filter = 1";
# etc.
"kernel_tunables" slist => getindices("sysctl");
---------
To me that looks just plain wrong: "sysctl" is surely a simple variable, not an
array. Yet I think I've seen this occasionally over the months, as though it
is a a correct and accepted way of working.
Can someone point to the documentation that explains this syntax and way of
working, please?
Thanks.
