But not in practise writing code ...

Right.

All global variables are dynamic/special but not all
dynamic/special variables are global ...

Good paper ...

  Lisp is Loose!

  The traditional attitude towards Lisp holds that it is
  useful only for esoteric amusements and Artificial
  Intelligence. The appearance of Multics EMACS as a Honeywell
  product is the death knell of this view. Now, a mainframe
  manufacturer is offering a system utility program written in
  Lisp; a program intended for heavy use by the general user
  community. The special properties of Lisp, which make
  extensibility possible, are a key feature, even though many
  of the users will not be programmers. Lisp has escaped from
  the ivory tower forever, and is a force to be reckoned with
  as a system programming language.

I don't know, maybe the ivory tower has just changed form :)
