I doubt that the extra time taken to link in 'everything else'
(already compiled) is the major barrier to experimenting with the byte
code interpreter ;-)  Many such experiments involve changing the byte
code itself, and hence the byte code compiler also.

PS.  When you start a new topic, start a new thread instead of
piggybacking on an existing thread.  Thread-aware readers typically
present a list of one line per thread and expand on request.  If I
were not reading the thread on PEP 317, I would not have seen this.
