Recent changes resolved issue 002, so we no longer need to indicate that
it's expected to fail. Other small changes to the type checker have
made things like type variable numbers change slightly.
This change partially reverts changeset c620cbf2, which fixed#296,
which was about supporting `:t (~)` in the REPL.
As of this change, `:t (~)` will no longer work in the REPL.
The regression test for issue #296 is removed.
Fix some minor conflicts in the test suite.
