This thread strongly reminds me of Readonly error on $_. In his response, merlyn displays some trick using the can method. /me thinks it can be applied here also. Saves the use of UNIVERSAL, but uses eval. 
if eval( $r->can('can')) {
    #we have an object
} elsif ref( $r) {
    #we have an unblessed reference
} else {
    #no reference at all
}

Merlyn's solution looks somewhat cleaner to me. What do you think?
