Recognizing Type of Reference

Is there a way to tell what type of reference a variable has... ie:

$mystring = \%MYHASH

How can I tell that $mystring is a hash ref, instead of a normal variable, an anonyomous sub, or an anonyomous array?

$mystring = \%MYHASH;

use the ref keyword

ref $mystring will return 'HASH'

Other possible ref types are

SCALAR, ARRAY, HASH and CODE (there are others)
