What about an EXPLICIT naming scheme for built-ins?

I think you're missing in this function a first line of
                a = list(arr)

But otherwise, yep, this sure looks right, except that I'm not sure
about the need for the try/except (can't hurt, but if not needed it
might be better to make life simpler by removing it).  Wouldn't...:

def isorted(seq):
    a = list(seq)
    heapify(a)
    while a: yield heappop(a)

work just as well?  What else but an empty a could trigger IndexError?
And if it's empty we're out of the ''while', so...
