Hmm, that's rather invasive to change the grammar and make these reserved words. I'd rather go with something less invasive by modifying 2.9.1 to special-case special built-ins that take arguments which can affect the current environment, if that is possible. At any rate, the standard itself is already affected by this: line 74321 (export EXAMPLES) lists: Set and export the PATH variable: export PATH=/local/bin:$PATH without "" quoting of $PATH, so either we need to follow through with the intention of specifying ksh88 behavior of not needing the "", or we need to fix the example. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
