Re: [Jython-users] jython to java?

[John M. <joh...@ya...>]

Yes, I not only used vanilla Jython but also used Java classlibs for
I/O and checksums instead of Python.  I originally used Python but
started using Java where I could to help performance.  That wasn't
enough and so then I started switching completely to Java.

Maybe there's a market for this sort of scenario.  Use a subset of
Jython in exchange for the ability to switch to Java after the
prototype solidifies.  Maybe both languages would benfit from
collaboration.

Multiple inheritance?  Yes, it's upsetting to me that the Java techs
left this out and have the nerve to defend their gutless decision with
bs.  In reality, Java does support multiple inheritance.  Well, in one
necessary case where the Java techs painted themselves into a corner...
the ability to inherit from Thread and one other class.  They don't
support this explicitly... no, that would require admitting their
error.  Instead they hatcked the language itself to get that it.  Ugh. 
That's makes two mistakes.

CPython?  I'm not sure about that anymore.  It's faster than Jython in
most cases but I have multi-threaded apps... on HP.  Maybe I misused it
but CPython crumbles... each thread taking a turn with the
interpretter.  The performance falls to near zero.  Correct me if I'm
wrong but the micro-threads in stackless Python is no better.
