Comment:

 Thanks for the patch @bor0. Removing the `is_object()` call makes sense.

 The change to the `count( $args )` call could actually increase the number
 of times it gets counted. Currently the count happens exactly once for
 every call to `apply_filters()`. With this change in place the number of
 times the count happens is equal to the number of callbacks attached to
 the filter where `accepted_args` is greater than or equal to the number of
 arguments passed to the filter. Worth some more thought.
