I am very curious to know what the difference is between send and public_send. E.g.:
class Klass
def hello(*args)
"Hello " + args.join(' ')
end
end
k = Klass.new
k.send :hello, "gentle", "readers" #=> "Hello gentle readers"
k.public_send :hello, "gentle", "readers" #=> "Hello gentle readers"
Can someone please explain the difference?

Unlike send, public_send calls public methods only.
Example:
class Klass
private
def private_method
puts "Hello"
end
end
k = Klass.new
k.send(:private_method)
=> "Hello"
k.public_send(:private_method)
=> `public_send': private method `private_method' called for
#<Klass:0x007f5fd7159a80> (NoMethodError)
