pub static cadef_cache: Mutex<[Option<Box<cadef>>; 8]>Expand description
Port of static Cadef cadef_cache[MAX_CACACHE] from
Src/Zle/computil.c:973. The LRU cache holds parsed
_arguments defs keyed by the raw arg vector — get_cadef
scans linearly, returns on first match (arr-compare on defs),
and on miss evicts the entry with the oldest lastt slot before
inserting the freshly parsed result.
