S iniciativou pokra\u010dovat v diskuzi vystoupil Hans Peter Anvin, jeden z kl\u00ed\u010dov\u00fdch v\u00fdvoj\u00e1\u0159\u016f j\u00e1dra ve spole\u010dnosti Intel a tv\u016frce projekt\u016f jako syslinux, klibc a LANANA, kter\u00fd pro j\u00e1dro Linux vyvinul syst\u00e9m automatick\u00e9ho montov\u00e1n\u00ed, implementaci RAID 6, ovlada\u010d CPUID a x32 ABI. Podle Anvina, kter\u00fd je autorem mnoha makro p\u0159\u00edkaz\u016f a assemblerov\u00fdch vlo\u017eek v j\u00e1d\u0159e, se jazyky C a C++ od roku 1999 v\u00fdznamn\u011b posunuly vp\u0159ed a jazyk C++ se stal vhodn\u011bj\u0161\u00ed pro v\u00fdvoj j\u00e1dra opera\u010dn\u00edch syst\u00e9m\u016f ne\u017e jazyk C. <\/p>\n

Funkce, pro kter\u00e9 bylo d\u0159\u00edve nutn\u00e9 pou\u017e\u00edvat specifick\u00e1 roz\u0161\u00ed\u0159en\u00ed GCC, je nyn\u00ed snadn\u00e9 realizovat ve standardn\u00edm C++, a v mnoha p\u0159\u00edpadech pou\u017eit\u00ed C++ povede k vylep\u0161en\u00ed infrastruktury bez rozs\u00e1hl\u00fdch zm\u011bn k\u00f3du.

Anvin pova\u017euje C++ za preferovan\u011bj\u0161\u00ed ne\u017e Rust, proto\u017ee ten se zna\u010dn\u011b li\u0161\u00ed od jazyka C co se syntaxe t\u00fd\u010de, je nezn\u00e1m\u00fd pro sou\u010dasn\u00e9 v\u00fdvoj\u00e1\u0159e j\u00e1dra a neumo\u017e\u0148uje postupn\u011b p\u0159episovat k\u00f3d (v p\u0159\u00edpad\u011b jazyka C++ lze k\u00f3d p\u0159ev\u00e1d\u011bt po \u010d\u00e1stech, proto\u017ee C-k\u00f3d lze kompilovat jako C++).
