Tests fail with Moo 2.002002

[eserte]

My smoker machines started to report the following test failure:

Class::XSAccessor: invalid instance method invocant: no hash ref supplied at /home/cpansand/.cpan/build/2016062218/Test-Proto-0.02
7-rhfIDA/blib/lib/Test/Proto/Base.pm line 203.
# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 255 just after 1.
t/Test-Proto-ArrayRef.t ............... 
Dubious, test returned 255 (wstat 65280, 0xff00)
All 1 subtests passed 
... (etc., all subsequent tests fail in the same way) ...

It seems that the problem is caused by the latest Moo version. Statistical analysis of test reports from my machine (negative theta is bad):
