Not if the loaded module uses defvar:
(defvar SYMBOL &optional INITVALUE DOCSTRING)
Define SYMBOL as a variable, and return SYMBOL.
You are not required to define a variable in order to use it,
but the definition can supply documentation and an initial value
in a way that tags can recognize.
INITVALUE is evaluated, and used to set SYMBOL, only if SYMBOL's value
is void.
