marshal

    cfunction

    (marshal x &opt reverse-lookup buffer)

    Marshal a value into a buffer and return the buffer. The buffer can 
    then later be unmarshalled to reconstruct the initial value. 
    Optionally, one can pass in a reverse lookup table to not marshal 
    aliased values that are found in the table. Then a forward lookup 
    table can be used to recover the original value when unmarshalling.
