It would be nice if deep equality checking and deep cloning of objects was
included in the standard library. Has there been any proposals around
including these in the past?

It seems like this model can be abused in the same way that having separate
methods for assign operators can be abused. I think having separate
operators and automatically using `[[plusOp]]` if `[[assignPlusOp]]`
doesn't exist is an easier programming model. People who need the extra

I forgot to mention in my last email that I'm looking for a champion for
this proposal.

Hi everyone,
I've been working on implementing operator overloading and would like to
submit a proposal.
I think operator overloading would be a useful addition to the language.
In particular I think it would be useful for defining operations on common
mathematical object types such as complex nu
