   Would be nice, though I think it should be decided on a per-module
   basis.  There are some modules that it may be worth deprecating and
   leaving undocumented, perhaps.

Certainly each module will have it's own doc patch.

However, i strongly discourage leaving things undocumented.  For some,
undocumented might mean "don't use".  For others (who peruse source
code), it might mean "implementation so stable, it's self-documenting".

Better to be explicit: If you want to deprecate something, the
documentation is ALSO a good place to make that clear.

Another benefit to documenting stuff that you want to deprecate is that
the sifting process may reveal bits or techniques you want to keep.

   The ‘accumulate’ API doesn’t lead to more concise code, but it leads to
   “non-standard” code, which makes it unappealing to me.

I can understand this point somewhat (what is unfamiliar often seems
non-standard).  However, i still fail to understand your sentence above;
do you mean "the latter" == "(ice-9 accumulate)"?

In any case, the API does indeed lead to more concise code, if the
original code that it replaces is `cons' plus `reverse!'.  But that's
neither here nor there...

   Setting $GUILE_LOAD_PATH and $GUILE_LOAD_COMPILED_PATH appropriately
   should be enough.

OK, i'll give moving the module to ttn-do a try.
