I'm doing some updates of the documentation. I hope it's not too late for 10.1. Rafael earlier said that bytes_to_utf8() probably should no longer be considered experimental in perlapi. Here is a list of all the functions marked experimental. Which of these can be removed from the list. addmad append_madprops apply_attrs_string av_create_and_push av_create_and_unshift_one bytes_from_utf8 bytes_to_utf8 clear_placeholders create_eval_scope delete_eval_scope do_op_xmldump do_pmop_xmldump emulate_cop_io fetch_cop_label find_uninit_var get_isa_hash get_re_arg gv_fetchmethod_flags hv_backreferences_p hv_copy_hints_hv hv_delete_common hv_iternext_flags hv_kill_backrefs hv_store_flags mad_free madlex madparse newGP newMADPROP newMADsv newTOKEN new_warnings_bitfield newXS_flags op_getmad op_getmad_weak op_refcnt_dec op_refcnt_inc op_xmldump pad_peg pending_Slabs_to_ro Perl_signbit pmop_xmldump prepend_madprops refcounted_he_chain_2hv refcounted_he_fetch refcounted_he_free refcounted_he_new refcounted_he_value start_glob store_cop_label sv_2num sv_catxmlpvn sv_catxmlsv sv_free2 sv_kill_backrefs sv_release_COW sv_setsv_cow sv_utf8_decode sv_utf8_downgrade sv_xmlpeek token_free token_getmad utf8_to_bytes xmldump_all xmldump_eval xmldump_form xmldump_indent xmldump_packsubs xmldump_sub xmldump_vindent
