Stop inferring bot/static when types/regions are unconstrained. Also, some other changes that came up along the way: - add a 'blk' region for the current block. - detect unused type/region variables. 2012-04-30 17:37:58 +00:00			`fn main() {`
test: Update expected compile-fail message for E0282 2015-05-05 16:22:20 +00:00			`let _foo = Vec::new();`
Add more detail to type inference error When encountering code where type inference fails, add more actionable information: ``` fn main() { let foo = Vec::new(); } ``` ``` error[E0282]: type annotations needed for `std::vec::Vec<_>` --> $DIR/vector-no-ann.rs:2:16 \| LL \| let foo = Vec::new(); \| --- ^^^^^^^^ cannot infer type for `T` \| \| \| consider giving `foo` the type `std::vec::Vec<_>` with the type parameter `T` specified ``` We still need to modify type printing to optionally accept a `TypeVariableTable` in order to properly print `std::vec::Vec<T>`.
