Works by changing things to:
<pre>
$ cat foo.pp
user{'b':
}
notify{'a':
require => User['b']
}
file{'/tmp/a':
} <- User<||>
$ puppet apply foo.pp --trace --noop

Bug #7422: undefined method `<<' for {}:Hash when combining resource chaining,
metaparameters, and autorequire

So I was talking with Markus and Dan about some weird autorequire behavior, and
ran into this. Assume you have the requisite files in /tmp:
# tree /tmp
/tmp
|-- a
| `-- b
`-- c
Then, if you run this manifest:
# autocycle.pp
file { "/tmp/a":
ensure => absent,
force => true,
}
file { "/tmp/a/b":
ensure => absent,
content => 'foo',
before => File['/tmp/a'],
}
file { "/tmp/c":
ensure => absent,
content => 'bar',
}
File['/tmp/a/b'] -> File['/tmp/c'] -> File['/tmp/a']
...you get this:
[root@puppet learning-manifests]# puppet apply --trace autocycle.pp

undefined method `<<' for {}:Hash on node puppet.localdomain
What it SHOULD do is reverse /tmp/a/b's autorequire of /tmp/a (to avoid the
cycle we would otherwise get), then delete /tmp/a/b, /tmp/c, and /tmp/a in that
order. Instead, we have an exposed internal Ruby error. Any clues?
