Every time I see things like the following I cry a little inside:

The syntax is inelegant, but the concept is straightforward and simple and not
worth tears.
"I need a thing called Foo, which can be found here, or here, or here. Use the
first one found."
In principle this is not terribly different from the idea of a search PATH
when looking for an executable, except the executable can be found under
different names as well as different locations.
Now we're talking about having to add __preview__ into that mix too?
As I understand it, Guido nixed that idea. (Or did I imagine that?) Preview
modules will be just added to the std lib as normal, and you have to read the
docs to find out they're preview.
