There's no way to refer to bar if foo.bar is in scratch.u

[mitchellwrosen]

If a Unison file has foo.bar bound...

foo.bar = ...

then there's no way to refer to something named bar, outside the file:

whatever =
  ... bar ... -- resolves to `foo.bar`

This seems inconsistent with how suffix-based name resolution works elsewhere (i.e. if both bar and foo.bar are in the namespace, then bar unambiguously refers to bar, because it's an exact match), and furthermore is a big problem for operations like update, upgrade, and merge, which have a print-then-parse loop.
