CIRCLE WITH A DOT

@fasterthanlime bonus points if it's reversible. That is, I'd like to stick #[!author_is_lazy_just_gc_everything] on the top, and:

1. Write new code like the lazy bastard I am
2. Be able to go "oh shit, ot does need to be fast" later, remove it, receive the justice of compiler errors
3. Decide "this fast code needs maintenance but I am lazy" - stick the #[!thing] on top on preexisting, correct rust code, and only then add stuff.

@fasterthanlime support a "slow but correct" mode. Rust's tradeoff is "fight the compiler hard, but resulting code is fast and correct". I'd like an option for "less compiler fighting, slower is OK, less correct is not OK". Something like "implicitly wrap all my shit with garbage collection". I'd like Go-level performance with rust-level correctness.
