UnboundMethod#==

(untyped other) -> bool

meth == other_meth → true or false

#define unbound_method_eq method_eq

Two unbound method objects are equal if they refer to the same method definition.

Example

Array.instance_method(:each_slice) == Enumerable.instance_method(:each_slice)
#=> true

Array.instance_method(:sum) == Enumerable.instance_method(:sum)
#=> false, Array redefines the method for efficiency

Ruby version changes

3.2
- UnboundMethod#== returns true if the actual method is same. For example, String.instance_method(:object_id) == Array.instance_method(:object_id) returns true. [Feature #18798]
