Something like that, in leu of literal scopes ( which would have a
hierarchy ) might work out.
I'm not trying to shoot down your idea, I just want to understand it, and
we approach things differently.
I think in the end we want to get to
interface Scope {
Scope getParent()
Resolve()
Get()
Put()
}
before calling a function/lambda
Scope scope = new Scope(stack.peek())
stack.push(scope)
call function(scope)
stack.pop(scope)
> Stellar should have a _ special variable which returns the message in map form

> In order to support functions which operate on the whole message, we should
> have a special variable (_, keeping with the vaguely scala theme) which can
> return the entire underlying message. This map should be immutable.
