Convince me that nothing like the following exists in the
ports framework and /usr/src and I'd be ok with a change
*after* 4.0 release (repeats himself)

# Makefile.foo

FOOVAR=

  .
  .
  .

BARVAR=${FOOVAR}

baz:
     for i in ${BARVAR} ; do \
	 ${BLAP} $$i ; \
     done


To me, changing it right now on the eve of -release
would be gratuitous. Later I would be fine with it.

I still prefer /bin/sh being able to handle an empty
literal list but would yield to the desires of others.
