// the right order, and very early in the init sequence.  In particular, vdl
// registration and package variable initialization needs to occur before
// functions like vdl.TypeOf will work properly.
//
// This function returns a dummy value, so that it can be used to initialize the
// first var in the file, to take advantage of Go's defined init order.
