. . . so maybe there's some general syntactic relief for rw/ro that is
orthogonal to everything else. But that means it wouldn't be a
trait, a type, a sigil, or a twigil, if it's really orthogonal.
I don't just want to go with bare rw and ro markers because I think
they're too easy to confuse. It's more like we want an initializer
that says "lock this after I change it". If used on the initializer
of a declaration it would have the force of a readonly declaration.
Some variant on or near the =, in other words, that could also be
a variant on normal assignment . . .
Sounds like you want a way to specify single assignment. Maybe use ":="
or something similar to say that the assignment is really a definition.
Though probably that doesn't address the "is context is rw" issue. And
it's not clear to me what it would mean without something like "my" that
introduces a new scope . . .
