Comment (by jakubbis):

 We can obtain this goal e.g. in this way:

 {{{#!php
 <?php
 function has_term( $term = '', $taxonomy = '', $post = null ) {
         $default_args = array( $term, $taxonomy, $post );
         $args         = apply_filters( 'has_term', array( $term,
 $taxonomy, $post ) );

         $args = array_merge( $default_args, $args );

         $term     = $args[0];
         $taxonomy = $args[1];
         $post     = $args[2];

         $post = get_post($post);

         if ( !$post )
                 return false;

         $r = is_object_in_term( $post->ID, $taxonomy, $term );
         if ( is_wp_error( $r ) )
                 return false;

         return $r;
 }
 }}}

 ''has_term'' filter will allow to transform $term value before proceeding
 actual logic.
