How can I exract array values when using Object.send. See the example
below.

class TestSend

def test( arg1, arg2, arg3)
puts arg1
puts arg2
puts arg3
end

end

t = TestSend.new
t.send('test', 'hey', 1, 'rrr')

args = ['hey',1,'rrr']
t.send('test', args) #this throws an argument error, 3 for 1..

Thanks.

Use the splat operator to expand the array into individual method
arguments:

t.send(:test, *args)
