BTW, the correct terminology is “literal arrays”. “Immediate” is used to describe instances of SmallInteger, Character, and SmallFloat64, which are encoded directly in a tagged pointer, i.e. there is no “box” fir the object.

There was a change in the compilation of literal arrays from Smalltalk-80 v2 (blue book) to (a little before) the ANSI standard. Before, any unquoted string was interpreted as a Symbol, so #(nil true false) collect: [:t| t class] answered Array with: Symbol with: Symbol with: Symbol. The change was to interpret exactly these three unquoted strings as referring to the objects nil, true, and false. So now #(nil true false) collect: [:t| t class] answers {UndefinedObject. True. False}.
