How about minified JS? What would be the best? Consider the massive amount of machine (or even IR) code that each identifier, built-in function, loop, switch and all other "syntax sugar" aka high-level-language-construct represents..
Could well be, depending on the app, dunno.. it's still the case that on the whole practically almost each lexeme in a high-level language expands into a giant ball of opcodes.. ;)
"We're" (many) already doing that too via gzipped responses (faster to decompress than to compress == neat for web uses). That's my point, a higher language is already "compressing" machine representation (all abstractions kinda do), minification turns its lengthy identifiers into minimal "codes", then the gzip.
