Hello, Ivan.

In article <mailman.202.1464109329.1216.bug-gnu-emacs <at> gnu.org> you wrote:

I'm not all that familiar with variadic templates.  In the declaration
below, is the "..." token syntactically part of "typename..." or is
better regarded as part of "... Y"?

I also need to get a feel for what keywords can come before the "...".
Obviously "typename", but what about things like "class"?

Do you know of a good web page where these things are explained
completely and concisely, yet readably?  If so, please tell me!
