And my point is that we're not discussing the syntax of `lambda` but the
representation of function values.
[ I agree with the above, BTW.  I just don't think it is relevant to the
  problem at hand.  ]

Currently the vast majority of functions in Emacs's heap (i.e. function
*values*) get printed either as a symbol or as #[...] or as #<subr...>.
The (lambda ...) and (closure ...) cases are in the minority and I think
it would be good to try and eliminate these cases as much as possible
(we'll probably have to keep supporting it for backward compatibility,
but we can stop generating them ourselves).
