Here is another example, an axiom from propositional logic:

    (impl (impl p (impl q r)) (impl (impl p q) (impl p r)))

which, vertically indented in a transposed block, looks like this:

    * (                                               )
    *   i (               ) (                       )
    *   m   i p (       )     i (       ) (       )
        p   m     i q r       m   i p q     i p r
        l   p     m           p   m         m           *
            l     p           l   p         p           *
                  l               l         l           *

which, using transposed lines within the transposed block, finally looks like this:

    * (                                                                                           )
    *   *impl* (                               ) (                                              )   *
    *            *impl* *p* (                )     *impl* (                ) (                )     *
                              *impl* *q* *r*                *impl* *p* *q*     *impl* *p* *r*       *

This time I won't make any judgements. Could be good, could be bad, you decide.

Not sure if that example helps. You can make any programming language hard to read without some basic formatting. The way I would write the sexpr would be:

  (impl
    (impl 
       p 
       (impl q r))
    (impl
       (impl p q)
       (impl p r)))

It's clear when each section begins and ends and doesn't require complex parsing rules.

That looks clean, can't argue that.
