B. Stroustrup once inferred that C++ is a language, whereas in the Lisp or Smalltalk world, coders commonly try to provide a complete environment for programming in use, furthermore in describing a language's characteric, as in C++, if you are working on a UNIX system, C++ will sound, or feel, like a UNIX language, and if on the other hand you are working under DOS, it will feel like a DOS language.

If one maintains the view that the motivation of the coders for work listed on the cited cat-v webpage was to have accessible 9P for use on GNU/Linux, that such labour hours were soley pursued predating the release of the Linux kernel version 2.6.14 (on 27 October 2005), with its v9fs (http://v9fs.sourceforge.net/),† or otherwise delegated to coding languages' exercises and "proof of concept" endeavours, and, that Lisp coders' provision of an environment is complete, and, Elisp coders dispute the first paragraph's description of a language, then, I guess, the position of RMS is correct.

This sounds reasonable. v9fs has been in the Linux kernel since 2.6.14 and that
should let GNU/Linux application programs use 9P without modification. So why
would we want to modify apps like Emacs to implement 9P separately? What am I
missing here?
