Since what is happening is that "foo" is being added to a namespace, would it not be logical for the usage to be: \DeclareDocumentCommand foo {...}{...} ? Of course, usage this way at variance with that of "\newcommand" might cause confusion for an author. (Since I do not code for TeX, I have no idea whether it might "cost" more.) -- Bill
