Or more succinctly:

    %num_of_lines<file> = [EMAIL PROTECTED];

Interestingly, a stored reference would track the current number of
lines rather than taking a snapshot.  But you should definitely think
of it as storing a reference rather than the number of lines, because
the ref will certainly behave differently in string context.
