Subject: Find a `pass.TypesInfo.Scopes[]` that's not nil

If I had read the comment for `Scopes` in
https://godocs.io/go/types#Info I would have known that only a subset of
`ast.Node` can appear in the `Scopes` field. Tried ones until I ended up
with valid scopes.

Now that we have a valid scope, maybe we can find out if it's using
variables not declared within that scope.
