They are crippled compared to C++, because you have no control over the return
type of opCmp and opEquals, which means that you can't have expression templates
involving comparisons. That's extremely limiting.
It is limiting, but I don't know about extremely limiting. Eric Anderton's regex
engine didn't need them. And, if you really do need them, you can always define
the templates as regular names:
lessThan(a,b)
equals(a,b)
etc. Not the greatest, but not unworkable.
