Thanks for the reply, Tollef. My goal was to make the vcl_recv be 
smaller and easier to read, so, instead of using a magic value, I 
renamed the actual function (which takes full set of arguments) into 
foo_ex() and created a separate foo() -- which passes all the mandatory 
arguments plus the default values for optional ones to foo_ex().

Still, I'd say, module-creation framework should some day support 
optional arguments (supplying default values)...
