Hello,  
a short question: is it possible to use variable length argument lists  
and binding associated blocks to a method parameter at the same time?  
And if it is possible, how can I do it?

I trief the following with Ruby 1.8.2, but it didn’t work:

def test(&arg1,\*args)  
end

Of course I know, that according to the definition both modifiers have  
to be used with the last parameter.

You need to puts the arguments in the opposite order:

def test(\*args, &blk)  
end
