This module is quite ancient, and, in addition to these warnings, has not worked for some time. Some logic errors in hash-table-mapping (detecting len) and mapping-ref (detecting dflt), for example. Since noone has reported the brokenness I guess that means the module has no users. There is no practical way to accomodate a separate delete-proc, as hashx-remove! uses assoc. The use of delq! and others to convey the intended delete semantics is incorrect, since mapping-remove! actually presents and expects a different interface, that of hashq-remove!. There is no documentation. It seems the main purpose of this module is to associate hash and assoc procedures with a hash table, and so provide a single set of accessors (rather than one for each of hashq, hashv, etc.). This is more-or-less handled by both srfi-69 and rnrs hashtables. A short module, it is not hard to fix, though given all of the above it makes sense to simply remove it.
