is_overloaded

   if (is_overloaded($class_or_object)) { ... }

Returns a boolean indicating whether the given class or object has any overloading declared. Note that a bare "use overload;" with no actual operators counts as being overloaded.

Equivalent to overload::Overloaded(), but doesn't trigger various bugs associated with it in versions of perl before 5.16.

overload_op_info

    my $info = overload_op_info($class_or_object, $op);

Returns a hash reference with information about the specified overloaded operator of the named class or blessed object.

Returns "undef" if the operator is not overloaded.

See "Overloadable Operations" in overload for the available operators.

The keys in the returned hash are as follows:

class

The name of the class in which the operator overloading was declared.

code

A reference to the function implementing the overloaded operator.

code_name

The fully qualified name of the function implementing the overloaded operator.

method_name (optional)

The name of the method implementing the overloaded operator, if the overloading was specified as a named method, e.g. "use overload $op => 'method';".

code_class (optional)

The name of the class in which the method specified by "method_name" was found.

value (optional)

For the special "fallback" key, the value it was given in "class".

overload_info

    my $info = overload_info($class_or_object);

Returns a hash reference with information about all the overloaded operators of specified class name or blessed object. The keys are the overloaded operators, as specified in %overload::ops (see "Overloadable Operations" in overload), and the values are the hashes returned by "overload_op_info".
