Sorry.  Quotation marks are generally used to mark variant usage of
text, actual quotes being only a special case.  Specifically, the `uh,
"annoying"' form is quite commonly used to imply "the actual words
he used are unrepeatable in polite company".

Mostly one doesn't.  A buffer-local can be emulated by a specifier by using

(set-specifier buffer-local-variable local-value (current-buffer))

to modify it, and accessing the current buffer's value with

(specifier-instance buffer-local-variable)

I don't recall why the arcane incantation I recommended to you was
needed in your application.  It may be that some version of specifier-instance
would have been satisfactory but I didn't understand your need well enough
to give a more precise answer.

The situation is very similar to working with menus or Emacs-style
keymaps.  There are some conceptually simple tasks that the API
makes unnecessarily hard to do.
