A parameter holds a key and a thread cell, where the thread cell is used if the parameter hasn't been `parameterized`. The key is used to look for a thread cell in a parameterization that's found as a continuation marks. A thread cell is basically a mutable emphemeron hash that maps threads to values, plus a default value to use if there's no mapping for a thread. So, you probably want something similar, except probably using the key to look up a continuation mark instead of the parameterization indirection, and then using "resume cells" instead of "thread cells". -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
