Behaviour of Puppet when multiple classes of the same name are defined

Hmm:

class one {
    notify { "one": }
}

class one {
    notify { "two": }
}   
include one

And I get:

luke@phage(0) $ test.pp
notice: one
notice: two
luke@phage(0) $

Strangely, I just ran your code and got the same behaviour you're getting (that is, only the first notice). Even stranger, I added my 'notify' resources to these classes and got my new behaviour again *with* all three notices:

class mysql { 
    notice('This is a load of the MySQL class') 
    notify { one: }
}
class mysql {     notice('This is a load of the second MySQL class') 
    notify { two: }
}
class mysql {     notice('This is a load of the third MySQL class') 
    notify { three: }
}
include mysql

Returns

luke@phage(0) $ test.pp
notice: Scope(Class[mysql]): This is a load of the MySQL class
notice: Scope(Class[mysql]): This is a load of the second MySQL class
notice: Scope(Class[mysql]): This is a load of the third MySQL class
notice: two
notice: three
notice: one
luke@phage(0) $

So, I don't know what the bug is here, but there's definitely a bug.

Marking #966 as a duplicate.
