I too get that error if reading from test.yaml fails. Then $yaml silently becomes undef, the later use of $yaml->[0] autovivifies it into an array reference, and then it's not a blessed reference, and calling write on it fails.

I suggest to use the LoadFile and DumpFile functions instead, which seem to do proper error checking.
