Hi,

I'm implementing SRFI-128 and got some trivial comments and questions.

[Comments]
- make-vector-comparator contains ']]' but no '[['. Seems not needed.
- In description of comparator-if<=>, <object1 doesn't have >
- comparator-if<=> doesn't say the comparison is done for given
<object1> and <object2>.
  it is rather obvious in which order should be done but might be
helpful to specify it.
- Test case contains fake-hash-salt but no definition.

[Questions]
- Should hash functions signal an error if given obj type does not
match the type of function?
  e.g. (boolean-hash 'a) ;; -> ?
- Should comparator-register-default! affect comparators already
returned by make-default-comparator?
- Default comparator of comparator-if<=>. Should comparator-if<=>
evaluate (make-default-comparator) each time or it can be the same
object?
- I'm implementing this SRFI atop SRFI-114 and it seems test case requires
  comparator-ordering-predicate to return the procedure passed to
make-comparator.
  Is this required by the SRFI?

Cheers,
