Unnecessarily long type name in Ch 13

[xStrom]

In chapter 13.3, in listing 13-26 and 13-27 the new function declaration is:

pub fn new(mut args: std::env::Args) -> Result<Config, &'static str>

Isn't the use of std:: here too much? Is it idiomatic to write that type out fully even though we already have use std::env; in the same source file and could use env::Args?
