True, but Packer isn't a zipping algorithm, just a minifier/obfuscator, 
it can still be gzipped; it'll be 7.9KB. But indeed, google closure's 
code is gzipped 6.77KB (according to google). So it might be that Uglify 
gzipped is as small or smaller as Packer gzipped. I'll set up an 
uglifier the week after the next.
