I should really (as I considered doing) have changed my sig back to "Perl is Huffman encoded by design" for that post.

Line noise is generally considered random (although if needn't be). Conventionally written languages of any sort generally present some form of structure. It may be incomprehensible to the reader, but it looks like it does have meaning or at least a pattern.

Perl on the other hand, especially in the small snippets you might find in one liners, can look almost like a random bunch of characters (line noise). That is more a function of Perl's succinct power than anything else.
