"set" actually wasn't common at all; in arc2 it is used only a handful of times in arc.arc, mostly to implement "=".

Eh, when I think about code use, I usually think about anarki — which is probably the problem itself, now that I think about it.

    $ find anarki/ -name '*.arc' -print0 | xargs -0 grep "[(']set[[:space:])]" | wc -l
It's not so many uses that it's impossible to update. Many if not most of these uses could admittedly be replaced with '=, and arguably this was the correct thing to do in the first place. It just seems like an odd decision, and I'm wondering if there's any specific reason for it.

In my opinion "set" is a better name for what "assert" used to do, and I think "set" was available since it was being used for a low-level operation for which in user code "=" is a better and shorter name.

Also, don't forget

"I worry about releasing it, because I don't want there to be forces pushing the language to stop changing. Once you release something and people start to build stuff on top of it, you start to feel you shouldn't change things. So we're giving notice in advance that we're going to keep acting as if we were the only users. We'll change stuff without thinking about what it might break, and we won't even keep track of the changes."
