JsonToken
sequences, needed for temporary buffering.
Space efficient for different sequence lengths (especially so for smaller
ones; but not significantly less efficient for larger), highly efficient
for linear iteration and appending. Implemented as segmented/chunked
linked list of tokens; only modifications are via appends.
