What about parameters implemented by modules?  The getters of those may
run arbitrary code, and may have side effects: e.g., imagine an
$AUTOINCREMENT parameter that returns an incremented-by-one value every
time it's evaluated:

    % repeat 3 echo $AUTOINCREMENT
    1
    2
    3
    % echo $AUTOINCR<TAB><Enter>

Wouldn't that print «5»?

Cheers,

Daniel
