| So what is progv used for?

  from the notes on PROGV in the HyperSpec (the ANSI Common Lisp spec):
  
    Among other things, PROGV is useful when writing interpreters for
    languages embedded in Lisp; it provides a handle on the mechanism for
    binding dynamic variables.

  I have never seen PROGV in use (apart from this case, which cries out for
  lexical bindings, not dynamic), but that doesn't mean it isn't useful for
  some people somewhere.
