I haven't been aware of SRFI-125 nor srfi-114 so far.

Taking hints I'll simply allow both orderings for the -table interfaces
and go with the srfi-1 ordering for immutable trees.

Furthermore the llrb-treetype had already grown in the meantime to
include a key? argument.  Adding one more for the here unused hash
function make it equivalent to srfi-114's comparators.  Thus I better
use the latter.

John, does a chicken implementation already exist?
