Got test cases to pass, after some major surgery
this test still doesn't pass, but at least it parses...
This test case now parses

I've done a slapdash job of fixing up the syntax; it didn't pass before,
and it doesn't pass now, but at least it parses...
Test now passes
added test case for issue 5927
with syntax fixes, this test case now appears to pass
fixed up issue-2185, but now it has a trait failure
more commits on issue 2185
after syntax fixes, these tests appear to pass
fixed the test case, hope it's still testing something
fixed this test case too
typestate is not planned for upcoming versions of rust....
renamed issue-2185 to issue-3429
fixed up syntax
fixed pattern, moved test to compile-fail
