in thread Huffman coding in pure Perl
Hmm. To be frank, I didn't know the semantics of the line is "not guaranteed to work in previous versions". I thought it was more like "only tested with versions this and above", and since I only have Perl 5.8 (5.8.8 to be exact), it was a natural thing to do.
I have nothing against older Perl versions, but I feel responsible if I don't clearly document it that I have only tested the module with Perl 5.8, and someone runs the module with an old version where it doesn't work.
