One thing about const that is slowly downing on this community is that
it will _not_ be used as often as in C++. It will be rare, and the
compiler and standard library should not require it without very good
reason. I think opEquals for classes is at fault for requiring const.
Interesting statement. Does this apply to immutable as well, or only
const? Because I thought const/immutable was supposed to make program
logic clearer etc... That implied it would be heavily used in "normal"
code. That's all a bit vague to me, care to clarify this a bit?
The statement doesn't apply to immutable because C++ doesn't have it.

You won't be able to call opEquals on immutable objects if opEquals would
require mutable pointer.
