+References of types REF, ARRAY, HASH, and GLOB are simple to get with the
+C<\> referencing operator. References to CODE come from anonymous
+function declarations (see C<sub>). SCALAR references come from such
+constructs as C<$sref = \substr($_, 3, 4);>. References to regular
+expressions are the printable results returned by the C<qr//> operator.
If the referenced object has been blessed into a package, then that package
name is returned instead. You can think of C<ref()> as a C<typeof()> operator.
