If I understand it correctly, that "?" doesn't actually mean
"writeable", right? It really means "unknown, and there are no
constraints on the context in which it was found that would cause
correct implementations that *do* recognize it to return something
writeable", yeah?

Similarly, am I correct in thinking that ?-IMM means "unknown but found
in a context that would cause a correct implementation that recognizes
it to refuse to return something mutable".

I'm not suggesting we change anything (and "?" seems to capture what I
wrote pretty well), just making sure I haven't missed anything.

cheers,
 -Brian
