I have sent an email to http://www.open-std.org/jtc1/sc22/wg14/www/contacts
and have received no response.

Here's the gist of what I was saying (?)
https://gist.github.com/d3x0r/f496d0032476ed8b6f980f7ed31280da (Please
feel free to comment? it does require a github account I guess? (Is there
anonymous comment I can enable?)

I am applying edits... and concerns mentioned here;

references, like `int &a` becomes mute(-ish). And there is some comfort
that the thing definition exists...
However, in the bullet library, when I interface with it to update and get
values, they are all reference types, so I must supply a thing to get the
value. The value does definitely exist within the engine, why is it I need
it to copy it; thereby occupying at least 2 pages in cache....

I don't know how else to reach them, or if there's a public comment forum;

http://www.open-std.org/jtc1/sc22/wg14/ is a readonly archive of a list;
and I've followed most links that would indicate there might be a way to
contact (...) community...?
