pub fn printparamnode(hn: &mut param, printflags: i32)Expand description
Port of printparamnode(HashNode hn, int printflags) from Src/params.c:6123. Real C
body is ~200 lines emitting the typeset/declare-style listing
for one param honouring PRINT_NAMEONLY / PRINT_TYPESET /
PRINT_KV_PAIR / PRINT_LINE / PRINT_INCLUDEVALUE /
PRINT_POSIX_READONLY / PRINT_POSIX_EXPORT / PRINT_WITH_NAMESPACE
and the per-paramtypes attribute table. Faithful direct port
of the common path: skip-on-.-prefix without WITH_NAMESPACE,
skip-on-PM_UNSET (with the POSIX preserve), AUTOLOAD gating,
then nam + =value via printparamvalue.
