  Technical?  You want the paren-less (orphaned? :) form to satisfy
  humans and some vocal humans object that it doesn't satisfy them.
  When does this become technical?  There probably cannot be technical
  reasons why some representation won't work.  This is also paren-free
  and has no ambiguity at all:

#1      defun example #11 #12
#11       foo &optional #111
#111        bar 1
#12       + foo bar

  But would you want to write code like this?  How about being forced
  to unless you can give _technical_ reasons why this won't work?  (I
  submit that there _are_ no technical reasons to reject this, only
  good reasons for humans to reject it.)  If you don't care to write
  code like that, and don't want to struggle to give any technical
  reasons for it, please accept that the people you're proposing your
  paren-less Lisp to do not want to write code in your syntax and
  object strongly to your implicit claim that unless they can defend
  their position on technical grounds, they should.

  If this is not what you expected, please alter your expectations.
