intx.dart, int32.dart, int64.dart should be in lib/src/ for package guide lines.
Also the unit tests should reference from 'package:fixnum/fixnum.dart'

Won't you have a problem here later with 'part of' not matching the library
name?

Good catch.

We can't use package: imports in the repo just yet, but I'm working on that.
(This patch is actually a step in the right direction since it updates this
package to the new layout.)

Yeah, we will. I tried making them sublibraries instead but this test (which has
to be manually run and has bit-rotted) accesses some private stuff in those
parts, unfortunately.

Right now, I'm just trying to get this to follow the new layout (in particular,
have its tests under test) so I can get "package:" imports working on the bots.
