Well, Expect is wonderful because in that it helps you when you're 
forced to drive an external app.  But it is a last line of defense.  
It's a hack.  I use perl because it is a powerful and expressive 
programming language.  All that goes out the window the minute I have to 
call system() and use a seperate executable (not to mention the fact 
that you fork several times needlessly in the process).  And what is my 
feedback?  An 8-bit integer, and maybe some STDOUT/STDERR output that I 
have to capture and parse?  How can you possibly compare that to the 
richness and elegance of returning complex data structures, like a 
native function can?  Or being able to throw execptions that are captured?

I only go outside perl when I have no choice.  And that is why I love 
Net::SSH::Perl. Native, pure-perl implementation of SSH.  Much needed 
and much appreciated.
