You should be implementing raise and raise-continuable in terms of call-with-prompt, abort-to-prompt, and fluids, just as catch and throw are implemented. See boot-9.scm, or "Prompts" in the manual, or http://wingolog.org/archives/2010/02/14/sidelong-glimpses, or ask me if you have questions :-) Andy -- http://wingolog.org/
