Don't worry about Pointed Head.  He's a well known troll in several 
newsgroups.

A long shot - maybe you have a package in one language you need to feed 
input to.  But that input must first be processed by a package in the 
other language.  Rather than rewrite everything, merge them together.

Or, perhaps you need to build the data preprocessor, and aren't familiar 
with the language the package is written in.

I agree it would be quite rare, but it's about the only reason I could 
think of people would need both languages.  I'm sure there are more, though.

I doubt that they'll ever have internetworking data structures, though. 
  Just not a need for it.

I agree with both of your points.  Both languages have reasonable means 
of accessing data.  I don't think there are any databases one language 
can access but not the other.

However, I wouldn't call those functions a "nasty mess".  But then I was 
writing C code > 25 years ago, and these are just wrappers around C 
functions.  And while there are other ways such as PDO, they also 
typically add an extra layer of overhead.  In a busy system, this may or 
may not be important.  However, if the system is that busy, I wouldn't 
be switching back and forth between languages, either.

I wouldn't have bothered looking up when a Perl module was shipped, either.

BTW - comp.lang.perl.misc added back since this is about both languages.
