What is the name of the style found in (e.g.) ISC BIND9:

ISC-style? (E/A)BNF-ish?

Personally I like (a) the open/close braces for better stanza navigation, (b) all statements/lines ending with semicolon.

(Something similar was used in (now-EOL) ISC DCHPd, and they've moved to "extended JSON" for their new DHCP server, KEA.)
