They only get printed if one is printing to a PostScript RIP, so one is
returned to the starting point:

PS == Turing complete programming language

PDF == flattened out document representation

hence

PDF < PS

and to make a PDF from a PS stream one _must_ parse and flatten out
_everything_ to remove dependency on PostScript farther down the line.
