Wow... I had to read this post twice to spot the error.. even when you 
wrote "|! looks enough like !! to be confusing" I didn't get it the first 
time!

Anyway, now I understand you (I think:)

I think we should continue the summary of how this should all work using
primarily (:trails ...:), and consider <<|..|>> a shortcut. As the
discussion above illustrated so well, it may get too complicated with '|'
and '!' next to each other.

Some ideas for <<|...|>> though... does "<<| !CatA |>>" look better? Or 
how about <<!CatA!>>?  (Those are exclamation marks rather than bars).
Hmm... <<!CatA!>> and <<!!CatA!!>> don't look so bad to me... but I'd 
probably use (:trails !CatA:) and (:trails !!CatA:) anyway, they seem more 
readable to me.

/C

PS On what PITS-pages did you start writing the summary?
