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.

Or just collect::<Vec<_>>() when you have up doing everything in a lazy pattern and want a concrete type again.

Which I guess i typical stumbling block when the compiler can’t infer what type to collect into.
