Interesting. I did not know about #+BIND, but just today I came about
the issue where I needed file-local variables to be available both in
the org-export-before-parsing-hook and in macro expansion. I
circumvented the problem by picking the original buffer out of
`buffer-list' and temporaryly switching to that buffer with
`with-current-buffer'.

Now I wonder whether #+BIND is more elegant. But my macro expansion
function modifies a buffer-local variable. Does #+BIND allow for that,
so that the changed value is available in the original org buffer?
