There is an interesting discussion of definite relevance to ocaml over 
at LtU:
http://lambda-the-ultimate.org/node/1784

One of the main threads is the issue of what kind of continuations will 
be 'grafted' on to ocaml for the reference implementation of ECMAscript 
4.  The keepers of ocaml might want to wade in to this issue before 
someone else makes a 'de facto' decision as to which type of 
continuations will be part of the ``language''.
