One issue with this is that template functions can't be virtual.
You can work around it, but it's really putting barriers up to easy use
of the new const system, which I think is a bad thing.

I'd rather have virtual template functions, even if it means I have to
re-compile all subclasses when the vtbls get modified. Is there any
technicality causing it to be impossible to implement or just something
rather tricky?
You can have virtual template functions, but you have to compile your
entire application and all its libraries at once, or record the
instantiated virtual template functions somewhere and handle all
affected classes in a different phase of compilation.
If Walter merely forbid creating object files, it would be relatively
easy. It'd be a much larger change if you wanted to support compiling
files one at a time or creating libraries. Still possible, though.
