Please cite commits whenever citing line numbers.  I assume you mean
as of commit v5.27.8-10-gef7498d.

That unreachable code, in S_pushav, I had already fixed, in commit
0f3591f944, by the time I read your message.

No, because pp_entersub should not be checking
PL_op->op_flags & OPf_MOD.

The same thing concerning OPf_MOD applies.
