I still think it would be kind of nice to be able to write that as:
import pysqlite or sqlite3 as sqlite
(ditto for "from pysqlite or sqlite3 import <whatever>")
You could even do it as a pre-AST transform (similar to
try/except/finally) and not even have to go anywhere near the
implementation of the import system itself.
I've never been motivated enough to write a PEP about it though.
Cheers,
