`purecopy' usage in ruby-mode.el and python.el

[Dmitry Gutov]

Hi all,

I see some places in the above files where purecopy is called. But:

  Pure storage is allocated only while temacs is loading the standard
  preloaded Lisp libraries.

  (...)
  
  — Function: purecopy object (...)
  
  This function is a no-op except while Emacs is being built and dumped;
  it is usually called only in preloaded Lisp files.

I take this to mean that `purecopy' can only be useful in elisp files
that Emacs preloads during compilation, but not in ruby-mode, python, or
any third-party libraries. Is that true?

Can we remove its uses from non-preloaded packages?
