You have mentioned Icicles a number of times, and one of the main
reasons I have never tried it out is that it is not available on ELPA or
any kind of official repository.  I believe wrote about this a while
back, but according to [0], the main issue remains that your libraries
overwrite Emacs primitives, as you mention in the main file:

Is this really necessary?  Somehow all the other completion systems
appear to get by without these kinds of invasive changes, and it would
be a pity the barriers for trying out your package continue to be
unnecessarily high, if the functionality is so advanced.  At the very
least it would be nice if you could have your own ELPA, perhaps hosted
on Emacs Wiki to distribute these packages in a more standardised way.
