Overriding < and > isn't the biggest issue, even though BC issues with
conversions may definitely be a surprise. Bug biggest one is ==, which
may have a lot of very non-trivial effects if you make == return
"equals" when other functions (such as searches, hashes, etc.) may treat
them as not equal. It is quite a complex thing which is rife with
unexpected side effects, so I think it would be better if it were explicit.
