I hadn't heard of pythonsiphon, but I'm pretty familiar
with the Vaults of Parnassus. My chief concern isn't with the *quality* of
what's availabile in Python (and some of what's at CPAN is pretty grim in
this respect); it's the sheer *breadth* of what's at CPAN that makes it

ASCII<->EBCDIC conversion is pretty easy to implement in just about any
language, but it's also easy to make a typo somewhere when you're typing in
lots and lots of ASCII codes. I know; I've done it ;->
The advantage of the pre-existing Perl module is that someone's already
written it, and 500 others have probably beaten out the bugs; there's a
degree of confidence there that I wouldn't have for some time if I was
typing in my own solution from scratch. Not that I couldn't do it; just
that it'd take some time for all my typos to be sorted out.

PyPerl looks very interesting - hadn't heard of that either! Glad I
posted the original message, and thanks to everyone who's responded for
some really useful ideas. Reading through various newsgroup postings
on PyPerl courtesy of Google, it looks pretty robust as well, once you
get used to how it works.
For me, Perl has one big advantage over *every* other language. If I have
to write a one-off piece of code to do some relatively simple task, and I
know that I'll truly never look at that code again, I can rip out a solution
in Perl almost as fast as I can think. The problem is that that code
will be completely illegible to anyone else, including myself a few weeks
later, but as long as the job gets done and I don't have to worry about
it later, who cares what the code looks like? I suspect lots of
experienced Perl coders will nod their heads as they read this...
Using Python, that same task will take me a bit longer (although
nothing like it'd take using, say, C or Java), but the code will be
relatively easy to go back to at some later date. It'll be better
structured; the variables will have better names, and so on.
However, when speed of development is absolutely crucial, Perl can't be
beat. (Thinks to himself: "Please don't let this turn into yet another
Perl vs. Python advocacy thread")
