Actually, it's already implemented in autoconf.git, although it is not yet 
documented (can anyone demonstrate that they need it outside of autoconf?).
http://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=fdcbe00

Hmm.  Speaking of that, autoconf.git mistakenly mentions AS_FOR in the NEWS, 
even though it is an otherwise undocumented interface.  I'll fix that shortly.
