[Numpy-discussion] Some observations or questions about psyco &
pyrex  Perry Greenfield perry at stsci.edu Sat Feb 8 13:52:02
CST 2003  Both psyco and pyrex have some great aspects. But I
think it is worth a little reflection on what can and can't be
expected of them. I'm basically ignorant of both; I know a
little about them, but haven't used them. if anything I  say is
wrong, please correct me. I'm going to make some comments based
on inferred characteristics of them that  could well be wrong.
Psyco is very cool and seems the answer to many dreams.  But
consider the cost. From what I can infer, it obtains its
performance enhancements at least in part by constructing
machine code on the fly from the Python code. In other words it
is performing aspects of running on particular processors that
is usually relegated to C compilers by   I'd guess that the
price is the far greater difficulty of maintaining such
capability across many processor types. It also likely increases
the complexity of the implementation o
