I'm not sure about the specifics of how I'd want to set up the syntax,
but I don't see why the potential problems you bring up can't be worked
around.  Hell, just adding "let" to the assignment operation could clear
that up -- though I'm not convinced that's the best way to do it, because
I'm not sure how much I care about the addition of an additional
syntactic element there.

    while let item =3D get_item
