For example, there is a paragraph about history, going back to Landin's J. Alas, that history is a bit truncated, saying nothing about delimited control and particular cases of delimited control such as green threads, Concurrent ML-like threads, coroutines, generators. Since putting that much history into a report is improper, perhaps the section about call/cc can be abbreviated and extra material put into an appendix or other non-normative document.
Removed the history paragraph; it's both incomplete and not very helpful nowadays.
