I think (perhaps because of the name) that this could be confusing. I
don't have any intuition that "virtual.lower" would return a function
that calls the "lower" attribute instead of returning a function that
simply accesses that attribute.
If we're going to move away from the itemgetter() and attrgetter()
style, then we should be consistent about it and provide a solution
(or solutions) that answers all of these problems:
obj.attr
obj.attr(*args, **kwargs)
obj[key]
I'm not sure that there is a clean/obvious way to do this.
