A few months ago I was reading lots of SNMP MIBs (sming format), and

error recovery (when a line departs from the accepted format part-way
through) is not going to be easy.
sscanf's like constructs are also a possibility. ARRAY OF CONST is strong
enough to
implement it.
And there seems to be already a starting point:

Also someone already has implemented a scanf port for Delphi that's
based on "array of const" though the license isn't suitable for FPC:
