You're right. Fortunately, I don't think it's any different.

-TypeTuple of the function parameter types
+TypeTuple of the function parameter types. For C- and D-style variadic
functions,
only the non-variadic parameters are included. For typesafe variadic functions,
the ... is ignored.

Can you improve on that?
