I tried to follow your explanation but know less lisp than
perl, unfortunately.  Still your explanations made sense, thanks.

But i do wonder what you read out of my posts.  (I have 
intensively programmed perl for one year each day, btw).
It started when i said how surprised i was to find out
that it is apparently not easy to parse perl. 

And i surely didn't indicate that any other current
language had this problem (if it is really there).
