Thanks for the info. >> Sorry for my making-no-sense examples. --- I get inspiration from >> Racket to engineer my language :) > > An easier example would be > > (force (letrec ([x (delay (force x))]) x)) Yep. This is a black hole due to premature access to an uninitialized variable. I was interested in interaction between delay and (delimited) continuation, e.g. what are captured contexts.
