https://dlang.org/spec/const3.html says that there are two ways of "Creating
immutable data".
I disagree, there is also the third way:
auto int x = 1;
void f(ref immutable int r) { }
f(x);
This is neither literal nor cast to immutable data. It is the third way.
See also https://forum.dlang.org/post/[email protected] as a
hint about the issue whether it actually creates immutable data.
