I don't set a Reply-To (nor does the list), so you get me by default.

I'm not sure I see the point.  The whole idea of Perl Power Tools as  
I understand it is to make available the usual suite of Unix tools on  
platforms which are not typically deployment targets.  A perfect  
example of this is my own Lamp environment, a Unix layer on top of  
classic Mac OS.  Typical source packages make assumptions that don't  
hold on my system -- often the existence of certain system calls,  
headers, or utilities -- or have other dependencies on glibc or gcc.   
On the other hand, perl is rather portable, once you get around not  
having the infrastructure to run the configuration and build scripts.

Now that I have a working perl (miniperl, actually) I can simply  
download utilities like ls, tee, and tr instead of writing my own  
versions in C++ or trying to wrangle the GNU build system.

Having the requisite functioning C perl makes a pure-Perl perl  
pointless, at least in the context of Perl Power Tools.  Maybe  
there's another reason to write one, but I don't see how I as a PPT  
user would benefit.

However, I think a pure-Perl Bourne shell is a great idea.  :-)
