Well, you *can* - in a way:

irb(main):001:0> def foo(*a) printf "method called%p\n", a end
=> nil
irb(main):002:0> foo = lambda {|*a| printf "proc called%p\n", a}
=> #<Proc:0x1015c594@(irb):2 (lambda)>
irb(main):003:0> foo[1,2,3]
proc called[1, 2, 3]
=> nil
irb(main):004:0> method(:foo)[4,5,6]
method called[4, 5, 6]
=> nil

Kind regards

robert
