I personally want that "Rust#" to exist if nothing else to use it as a test bed for Rust features with real world usage. I think there are tons of small things we can do that will make Rust easier to use, but some of the issues with "spaghetti of global state" designs will never be not painful in the language. Some of them can be mitigated with better libraries (allowing granular Singleton field access without keeping locks on the global object), but likely not all of them will.
