I made a dialect once called VoqLisp in which a thread carried the dynamic bindings visible in the code which spawned it.
This then resembled POSIX environment variables: "FOO=bar command arg" and was handy in a similar way. You could use let to set up a bunch of parameters affecting the thread, and then create it in that body.
