We can of course do this:

I'm wanting the naive expansion of that syntax to do this:
variable=${var:1:1:=y}
... but it doesn't work. Can something like that be done?
(This is admittedly a non-answer, as I don't know whether there's a solution that's as succinct as you'd like.)
I would find that syntax (or something like it) very ambiguous. What would be assigned "y" in this case — `var`, or the slice of `var` that you were testing? Neither is obvious.
