At least in the Bro 1.4 source, the files in the aux/binpac/src
directory are C++ (plus "Flex++" and "Bison++"). The page at
http://bro-ids.org/wiki/index.php/BinPAC_Compiler
says
Scanning and parsing is done by flex and bison generated code. A user
can learn the formal grammar specification from aux/binpac/src/
pac_scan.ll and aux/binpac/src/pac_parse.yy under the Bro source tree.
The BinPAC language *itself* might have adopted some concepts from
functional languages, but the translator for the language appears to
be Boring Old C++.
