Comparison operators

[Joe Van Dyk]

Say I want to define all the operator==, operator!=, operator<=,
operator>, etc for a class.

I could've sworn there was a library (maybe in Boost) that helped me do
this (so I don't have to define all of them by hand).
Was I imagining it?

Thanks,
Joe

So, define them. What's stopping you?

Quite possible. What kind of "help" do you expect?

Would you be surprised if I told you it was Boost:perators?

Because in most cases, defining all of them duplicates knowledge. Which I
try to avoid. And it's tedious and boring.

A way for me to specify the results of a couple of the operators, and have
the others generated through some means.

Ah, thanks. That looks like what I was looking for.
