The obvious

doesn't work. Probably have to override the one from Object ? Even
though I don't really use polymorphism here.
override bool opEquals(Object b) immutable {
return value == (cast(immutable(C)) b).value;
}
Nope. Doesn't work (or compile) either.
Yes, opEquals for classes has a particular syntax:
http://ddili.org/ders/d.en/object.html#ix_object.opEquals
Remember that 'const' binds to immutable as well. The following works
with at least git head:
override bool opEquals(Object b) const {
auto rhs = cast(C)b;
return rhs && (value == rhs.value);
}
