It was the one and only prog. language I turned up where: overflowism goes to its long-overdue grave; paper standards exist, going back to 1980s; reasonably-mature compiler for all commonplace irons; no GC or other heavy runtime ball-and-chains.

IMHO it is possible to implement a sane (i.e. less than 50kLoc, say) self-eating compiler for the subset of the language I and others made use of (snip out the OOPisms; microshit, vax, etc. dead platforms support, other superfluous rubbish.)

Re: Keccak -- similar "glue factory" process, but orig. initiated by MP (I found no catastrophic flaw such as to disagree); must note that it suffers from same problem as e.g. Serpent (and all known symmetric ciphers) -- i.e. neither Keccak nor any other known hash algo rests on any number-theoretical conjecture, but instead all were made by the same process as the other "voodoo products" in the "hashes-PRNGs-symmciphers triangle" -- "it appeared to be hard to break for author himself, therefore Must Be strong".
