Right, this is the downside that I see with “repeat {}”.

This would require taking “forever” as a keyword if we supported “repeat N {",
something we wouldn’t want to do.
Another option is to make it a statement modifier, which wouldn’t require
taking it as a keyword (but also doesn’t read as well):
forever repeat { }
Personally, I don’t see this as a big enough improvement over “while true” to
be worth introducing complexity for.
