That does look cute (note that you can use parentheses rather than
newline-escaping to continue the line.) I assume it should come with:

from (xml.etree.cElementTree or xml.etree.ElementTree or
        elementtree.cElementTree or elementtree.ElementTree or
        lxml.etree) import ElementTree as ET

(Parentheses there are currently illegal.)

But should it also come with:

from xml.etree import (cElementTree or ElementTree) as ElementTree

and combined:

from xml.etree or elementtree import cElementTree or ElementTree as
ElementTree

and of course combined with explicit-relative imports:

from .custometree or xml.etree or elementtree import cElementTree or
ElementTree as ET

or is that all going too far? :)
