Echo JS 0.11.0

Really need for Safari to adopt this feature for it to be broadly applicable.  You should be able to use it now for server-side code environments like current versions of Node and Deno, looks like Bun doesn't have it yet..

It's a feature I really appreciate in C#, especially since you don't need to wrap into a closure anymore, it just inherits the containing closure, like JS/TS implementation.
