Why do we have transitive const, again?

[Adam D. Ruppe]

IMO immutable has taken a step *backward* a few releases ago,
and that's about all I've thought about it.

immutable string a = "lol";

auto b = replace(a, "lol", "rofl"); // used to work, now doesn't.


The thing is the immutable works well with normal functions, but
not with range templates. Ugh.



Other than that, the system kinda works, but I find I don't
use it very often, especially in classes. Perhaps that will
change with inout being finished.
