Ahhh of course. Personally I think opCmp includes o

You mean "object"? A class variable is just a handle to the

In some code I'm working on, my asserted when I've confirmed it
was correct. With the opCmp() overridden. 'this' refers to the
current object, so why doesn't the first one succeed?
class X {
int z;
this(int xx) {
z = xx;
}
override int opCmp(Object y){
X x = cast(X)

I'd say that's right and wrong.
Thanks for the rapid reply.

Honestly, in my opinion, drop this. Don't make it more
'pointer-like'. Unless there's a good reason, or it makes sense
(Mathematical), then don't. You keep having half the tests
using regular &(address) operator; wha

Well it depends . Why do you need a char[]? If
