old ticket exported from SLVM but needs a new TODO # and i need to bother to think about this more so i can either address it or remove the TODO from the code b/c what i'm currently doing works well enough.

}to avoid needing to parse lifetimes for functions, when returning a reference specify with a #[return] macro (or something) that a given slosh value is also the value that will be returned. This can dramaticaly simplify the macro code while allowing a user to still write code that compiles in rust but is also performant in slosh.
e.g. the extant value problem and some related cases.
