I presume that's the case here, since blink-matching-check-mismatch is
only used in the smie-blink-matching-check function which in turn is
used as a local variable for blink-matching-check-function.  So there's
probably not a problem.

Then again, I don't quite understand why smie.el was added to emacs-23
at all, it does not have seem to have any users there (as opposed to the
trunk where several programming modes use it already).

Regards,
