perldoc perlreftut, perldoc perlref.


Also something someone else pointed me at out-of-band is that the
Scalar::Util module has a `reftype' function that will return the
underlying type even for blessed objects:


   reftype EXPR
       If EXPR evaluates to a reference the type of the variable refer-
       enced is returned. Otherwise "undef" is returned.

           $type = reftype "string";           # undef
           $type = reftype \$var;              # SCALAR
           $type = reftype [];                 # ARRAY

           $obj  = bless {}, "Foo";
           $type = reftype $obj;               # HASH


Granted an object would probably count as a value in the situation at
hand this wouldn't be what you'd want, but it's nice to know.
