Just note that if the function is const or immutable, then
"typeof(this)" will be "immutable S!(...)", where as if you use
an actual "S!(...)" as your return value, you'll get a mutable
return.
This can make a difference depending on if or if not you can
strip constness by copy, for functions such as:
R!T save() const;
vs
typeof(this) save() const;
Just wanted to note it. It's a subtle difference that's often
forgotten.
