The perl script.  (The slang works fine.) Within the first day
of usage, I ran across a number of signed articles where the
demime perl script just deleted both the signed message and the
signature and left nothing.

Yup.

All I can say is that some messages I tried to read didn't work
for me.  One example that didn't work was a multipart/mixed
message where there were a couple text/plain parts and one
multipart/signed part.

Another thing I didn't like much about demime was that it
didn't show any indication what sections had been removed from
multipart/mixed, and didn't give any indication of where the
boundaries were for the sections of a multipart/mixed that it
did render. 

If "attachments" were removed, I'd like to know their type and
name.  When multiple text/plain sections are rendered, I want
to know where the boundaries were.  

It also seemed to make no attempt to render HTML message
sections.  In a multipart/alternative, I'd like just the
text/plain version, but if there is no text/plain, then I want
to see the text/html version rendered in a reasonable manner.

What I'm saying is that I couldn't.  I tried to bind the
commands to \e6 and \e7 using your slang file, but it didn't
work.  AFAICT, my copy of slrn always treats escape-6 and
escape-7 as command prefixes, not commands themselves.  I was
wondering what you did to make \e6 and \e7 work.

Python is a very nice object-oriented programming language.

www.python.org

It's byte-compiled and run on a VM (like Java, Perl, and many
others).  It's got a very extensive standard library that
includes things like MIME e-mail message handling modules that
let you do in 60 lines what took 3000 lines of Perl. ;)
