Quote from Donald Knuth for context: "[Floyd] was destined to be disappointed that his dream of a new, near-ideal programming language called Chiron was never to be realized--possibly because he was reluctant to make the sorts of compromises that he saw me making with respect to TEX. Chiron was "an attempt to provide a programming environment in which, to the largest extent possible, one designs a program by designing the process which the program carries out." His plans for the Chiron compiler included novel methods of compile-time error recovery and type matching that have never been published."
