Such doch hier im Forum mal danach ... afaik hat Hume da mal was gepostet
Richtig. Allerdings im Mod-Forum im Syntaxcoloring-Beta-Test-Thread
Das sah in etwa so aus:

Hier ist ein Fehler:
// some string literals if (a == '\\' || a == '\'' || a == '\"' || a == "\'hallo\'")

da sind ein paar Fehler drin
test:
#i\ n\ c\ l\ u\ d\ e <iostream>

Dann begannen Dennis und Brian an einer wirklich verzerrten Version von Pascal zu arbeiten, genannt 'A'. Als wir merkten, daß andere tatsächlich vorhatten, Programme mit 'A' zu entwerfen, fügten wir rasch zusätzliche kryptische Eigenschaften hinzu, und entwickelten daraufhin B, BCPL und schließlich C. Wir hörten auf, als es uns gelang, den Ausdruck
for(;P("\n"),R--;P("|"))for(e=C;e--;P("_"+(*u++/8)%2))P("| "+(*u/4)%2);
fehlerfrei zu compilieren.
Zu denken, daß moderne Programmierer versuchen würden, eine Sprache zu benutzen, die derartige Ausdrücke zuläßt, lag weit außerhalb unseres Verständnisses.

i know, aber was hat das (ohne codetags) hier zu suchen?

Uuppsss - sorry!
