I do not grant your basic assertion. Hoare had it right: "ALGOL 60 [was] a
language so far ahead of its time that it was not only an improvement on its
predecessors but also on nearly all its successors." That would definitely
include Algol68, which was a classic committee-designed nightmare.
Common Lisp came long after 1968, was committee-designed, and is by no means a nightmare. It's not a jewel like Scheme is said to be (wrongly IMO), it's a ball of mud, but balls of mud are best for solving muddy problems.
