Hello everybody,

is there a way to tell the `(read)` function not to interpret `|` as an "copy 
this verbatim" delimiter?

What I want to do is:
(read "(|| a b)") ;=> '(|| a b)
(read "(<| a b)") ;=> '(<| a b)
etc. - allow `|` as a symbol.

I know about readtables - dabbled with them before and they seem like the right 
tool for the job. But in this case, my last attempt was:

(make-readtable (current-readtable)
  #\|
  'terminating-macro
  read-as-symbol)

and I couldn't get the `read-as-symbol` function right. Also experimented with 
`read-accept-bar-quote` parameter but no dice.

Any help/pointers?
