As side note. Maybe someone knows, why rust devs chose an already used name for language changes proposal? "RFC" was already taken and well-established and I simply refuse to accept that someone wasn't aware about Request For Comments - and if it was true and clash was created deliberately, then it was rude and arrogant.

Every, ...king time, when I read something like "RFC 2789 introduced a sparse HTTP protocol." my brain suffers from a short-circuit. BTW: RFC 2789 is a "Mail Monitoring MIB".
