Nah, there's lots of times you need to specify the types of Vec, either because 1. You don't want the default `i32` integer type and this is just a temporary v

Nah, there's lots of times you need to specify the types of Vec, either because 1. You don't want the default `i32` integer type and this is just a temporary vector of integers. 2. Rust's type inference is not perfect and sometimes the compiler will object even though there's only one type that could possibly work. Edit: The <Vec<T>>::new() syntax is definitely never used though.
