Is there a speed problem with the sample implementation of (srfi 146
hash)?  It's a HAMT package written by Art Gleckler.

Note that fectors are a bit specialized: they are very fast for both ref
and set if you don't change the "current branch" very often, but slower if
you do.  Ordinary tree functional vectors have the same big-O no matter
what.  There will be a fector SRFI.
