Depends, but usually I recommend you put the defvar at top-level,
otherwise you have to put it at various places (everywhere it's
let-bound and everywhere where it's referenced).

Also, I strongly recommend those dynamically-scoped vars use a package
prefix, just like global variables (since they are fundamentally global
variables).
