Pod::Abstract::Serial - generate a global sequence of serial numbers.
Used to number Pod::Abstract::Node elements for identification.
This will cause problems with Pod::Abstract documents frozen to disk using Data::Dumper etc,
unless set is used to bump the number above the highest number read.
Or just serialise your document with $node->pod instead!
