[std-proposals] Explicit template parameters

Earlier this year on 25 March, I shared my idea to this mailing list of
using the 'explicit' keyword on template parameters as follows:

    template<explicit class T>
    void Func(T &arg)
        /* Do Something */

The idea was that you would have to write:

    int main(void)
        int i;


because the 'explicit' keyword would prevent automatic deduction of the
type T.

You can see my original post archived here:


That same week, another contributor made another suggestion that looked
similar to what I was suggesting, but which was very different in
functionality. My own suggestion I think got lost in the paperwork back and
forth, and so I would like to bring it to people's attention again now, as
I've shared the idea elsewhere and people seeming to be overwhelming in
support of it.
