The publicly available version of anic really isn't close to usable at
this stage and further development is happening in private (for the
time being, at least), so RosettaCode and I guess also introducing
others to ani is a bit premature at the moment. Have a look through
the mailing list archives for more details.
Having said that, do check back in a few months when (hopefully) anic
will be in a testable state. Sadly I am not working on anic at all and
Adrian has been pretty quiet, so I cannot promise anything, but from
what I've heard, Adrian is hard at work on anic.

Dan.
