How can I take an array, extract each top level value when using  
Object.send on an object?.. 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 outputs an argument error, 3 for 1.

Thanks

Use the splat op:

t.send(‘test’, \*args)
