macro names are case sensitive, to wit

peter@kapet:~$ cat martians
Martians = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, \
10.0.0.0/8, 169.254, 0.0/16, 192.0.2.0/24, \
0.0.0.0/8, 240.0.0.0/4 }"

block from $martians
peter@skapet:~$ doas pfctl -vnf martians
Martians = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8, 169.254, 0.0/16, 192.0.2.0/24, 0.0.0.0/8, 240.0.0.0/4 }"
martians:5: macro 'martians' not defined
martians:5: syntax error

for conversion to tables, keep in mind that references need the
surrounding '<' and '>'.
