==(p1)
public
Equality—Returns true if other_struct is equal to
this one: they must be of the same class as generated by
Struct::new, and the values of
all instance variables must be equal (according to Object#==).
Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joejr = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
jane = Customer.new("Jane Doe", "456 Elm, Anytown NC", 12345)
joe == joejr
joe == jane
