this is not needed.
The reason you use $::foo is because of the problem here:
$foo = "top"
class x($foo="class") {
notice($foo)
notice($::foo)
}
include x
this produce:
Notice: Scope(Class[X]): class
Notice: Scope(Class[X]): top
you need to guard against the accidental $foo which used to be much
worse with dynamic scope, so the code got littered with all this ::
rubbish.
$facts is globally reserved
class x {
$facts = {}
}
include x
Error: Evaluation Error: Error while evaluating a '=' expression,
Attempt to assign to a reserved variable name: 'facts'
You can never cause the problem that raised the need for $::facts to
exist, you can just use $facts and it's all sweet and
In general with Puppet 4 the needs for all the :: stuff is almost all
gone
