I've just checked, \commalistsentence is already on the wiki, but you have to
know it exists. (I'll check whether I can link to that page from somewhere.)
But there's no (high-level) way to apply certain commands to this list
elements, right?
Background: My real use case is a bit more complex. I use comma separated lists
to store author lists, but the authors themselves are saved in structured
variables. So, I'll need to reassemble the different name parts first.
So, nothing like
\commalistprocessandmakesentence[a,b,c]\commandforfirst\commandforinbetween\commandforlast
Probably to specific, right?
