Regarding the "hunks" he mentioned, here's what Guy Steele had to say about them when I interviewed him for Coders at Work: "I implemented a new data type called a 'hunk,' which was probably the biggest disaster in language design we ever put in. It was essentially a cons cell with more than two pointers. It was a desperation move because we were running out of address space on the PDP-10. Recall that the -10 only had an 18-bit address space. In a list, 50 percent of the pointers were dedicated to just maintaining the structure of the list, whereas with a threaded set of hunks, maybe only one-eighth of the pointers were dedicated to the threading of the chunks so you’d get better memory usage that way."
