I don't mind you being against those changes, but the changes so far are 
hardly "large". Ignoring the tests, both my PRs combined add meager 20 
lines. And that's for seven bug fixes.

By the way, you recently made changes to `save` methods in std.utf:

https://github.com/dlang/phobos/pull/6900
https://github.com/dlang/phobos/pull/6903

I'm not sure why you made those, but they touch the same kind of code as 
my PRs, and they actually fix the issue I was fixing, too. Are you 
planning on applying that pattern to all of Phobos, or just std.utf for 
some reason?

If you're going for all of Phobos, you might end up fixing issue 18657 
as a side effect. But removing RefRange.opAssign would still be nice, 
because it's just weird.
