As I just discovered (see above), dis.dis is happy to interpret byte
strings (i.e., strings in 2.x, bytes in 3.x) as direct representations
of Python bytecode.

There's also an open feature request[1] to allow text strings as input
in py3k, doing an automatic compile before passing the result to
dis.dis.
