"This is a matter where Pauan and I agree on the ideal semantics completely."

Quite the rare thing indeed.

"I seem to remember us advocating egal a few other times (though I don't think I've ever called it "egal")."

I personally haven't. I only recently started to actually care about egal because of Nulan using immutable objects.

I do remember us having discussions before about making "iso" the default equality in Arc, which is what wart does, but I don't recall us talking about cons mutability.

"I personally haven't."

Oh, well then welcome to the club. XD

I looked around for where I talked about this before, and I guess I was mainly thinking about this time: http://arclanguage.org/item?id=13701

I touched upon it in at least one other conversation after that: http://arclanguage.org/item?id=14596

However, I can't find any more than that. Maybe I just took it for granted at that point.

It is the policy I applied in Cairntaker. Cairntaker interns all immutable tables so they can be compared for deep equality even after some of their entries have been garbage-collected. Equality support is essential in Cairntaker since any value can be used as a table key.
