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)
