New submission from Matthew Suozzo <matthew.suo...@gmail.com>:

Given the increasing use of long `from typing import foo, bar, ...` import 
sequences, it's becoming more desirable to address individual components of the 
import node. Unfortunately, the ast.alias node doesn't contain source location 
metadata (e.g. lineno, col_offset).

This metadata would be comparatively easy to add, backwards compatible, and 
would enable more precise diagnostics e.g. lints.
