Nice!

I tried to run the tests in Gambit, but they use the R6RS #vu8 read
syntax. Changing it to #u8 works, but it might be worth changing the
tests to use a portable read syntax (perhaps just calling the `vector`
procedure to make vectors).

The next part it gets stuck is Gambit doesn't yet have SRFI 125
hash-tables yet. Should be a simple matter of writing a wrapper for its
native hash-tables.
