Hi Steve,
Can anyone on the list recall the original "bill of rights" for Pop-11 and its predecessors - that functions are first class citizens and that all data items can be compared for equality etc? I am looking for the original text and struggling.
This Wikipedia page https://en.wikipedia.org/wiki/First-class_function states: The term was coined by Christopher Strachey in the context of "functions as first-class citizens" in the mid-1960s.[4] https://en.wikipedia.org/wiki/First-class_function#cite_note-strachey-4 I guess there should be an entry for Pop-11 (+ Pop2? +Pop10?) in the table on that page.
