That sounds plausible---I think you're on the right lines.  You might
need a -U argument to compadd in that case, too.

Basically, you are (anybody is) on your (their) own in this type of

so complicated we've forgotten and won't remember again without devoting
hours to remembering why we thought it was better to forget in the first
place.
