I have no idea what the actual application is, what it does or the situation in hand... :o)

with that disclaimer in mind, perhaps you should review your indentation and coding model :o)
I've found several examples of lisp code on the Net (sadly, I am more familiar with Prolog than Lisp) which look pretty normal.. I know I'd be a bit taken aback if I saw a pageful of parantheses :o) (yes, yes, I know.. get an editor that can match parentheses)

Some links to Lisp code and coding style(if anyone is interested)
AutoCad routines
Lisp coding style
has some stuff on Lisp style indenting

just my <$0.02
