Why generators, when delimited continuations can implement them trivially? It seems to me that -F- is a worthy successor to call/cc [*]. Andy [*] To implement a delimited call/cc on top of prompt and abort, you would need an additional operator that captures a partial continuation, but without unwinding the prompt. I understand that Racket does this. -- http://wingolog.org/ _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
