Look through some really old Lisp code sometime. SBCL is highly readable despite being: 1) 25 years old and touched by tons of different people since then; 2) a program that does some really complicated things in a pretty small space (~60 KLOC for the arch-independent portion).
When you see (def-ir1-transform ...) in the SBCL source, it's immediately obvious what is about to come along (at least if you know about compilers). Similarly old C code (eg: GCC) is completely incomprehensible in comparison.
