I think the idea here is that such a function may be named by a typedef or dependent typename. The first thing in that list is - an identifier associated by name lookup with one or more declarations declared with a dependent type So if an argument is declared with dependent type, the function identifier is associated with a dependent type by name lookup, hence dependent. -- [ comp.std.c++ is moderated.
