Here is a proposal that tries normalizing the special case of passing zero values as well: <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=17474> This "use only the first value in non-multiple-value accepting contexts" is similar to what Lua uses in the context of "..." argument lists. -- David Kastrup
