I would also be very suspicious of relying on keys and values having the same order, they probably will (might even be guaranteed) but I'd still prefer not to have an unsorted keys call as a hash slice. Instead of: 
@$default{ keys %$config } = values %$config;

...I'd probably write: 
my @ids = keys %$config;
@$default{ @ids } = @$config{ @ids };

[download]
...this is also less likely to get updated to be "bad".
