But then, you don't call `boundp' on variables. You call it on symbols.

AFAIK (but I could be wrong, corrections welcome!) there's no explicit
notion of variable in Emacs Lisp, i.e. you cah't "have" a variable
object and manipulate it directly.

That doesn't mean they don't exist -- I fancy them living in the grey
area between symbols and bindings.

Again, the Elisp manual ("12 Variables" and, linked from there, "9
Symbols") makes for a good reading.
