One more drawback, actually: in the model I described the immutable
string assumes a flat buffer. So if you have a rope-based mutable
thing, passing it somewhere means you have to flatten first. In
practice, for

I'd like to understand/challenge this statement. Is this bad for
performance because you have to check the extra SHARED flag on write?
So I tho

Was there discussion about whether string buffers should be refcounted

Ref counting versus GC is determined on a case-by-case basis in Servo.
There's no one-size-fits-al

It sort of grew out of an IRC conversation over the course of 20 mins or

I absolutely agree that
Immutable strings sound good to me.
How hard would it be to add UTF-8 strings to Spidermonkey? JSString already
has a lot of "modes", perhaps one more wouldn't hurt :-). I'm imagining
that for anything that required UTF-16 (charAt etc) you'd convert the
string internals to UTF-16, and for passing
