So which one makes more sense:
echo `ls \`echo \\\`ls | grep elisp\\\`\``
Or
echo ${ls ${echo ${ls | grep elisp}}}
And what do you do with shell code that is everywhere like this:
echo ${SOMEVARNAME}_SUFFIX;
Perhaps we can detect if ${NAME} is a defined variable and treat it differently?
I can just see people wondering why ${ls} doesn't work the way they expect if
they
export ls="/path/to/my/linux/stuff"; A contrived example as well.
