While I like them a lot, it's time for them to go:
1. It's hard to remember which one does what
2. They've failed to catch on
3. No operator overloading for them
4. They are only rarely needed; a special operator is not justified
Before trashing everything some useful compromise between the two extrema
(having many complex operators, and having nothing) can be found. I think Don
said something about this.
Regarding "no operator overloading for them", it's a matter of will, with the
opBinary operator syntax it's easy to use them too :-)

Actually you could easily "overload" them with opCmp, you just need to
return a float.
class NonComparable {
float opCmp(NonComparable other) { return float.nan; }
};
void main () {
auto a = new NonComparable;
assert(a !<>= a);
}
