Subject: Arrow operator with dash instead of equals (->)

Hi, all,

Is it possible to use -> as a method name in Ruby?

This code:
        
        class A
          def ->(arg)
            puts arg
          end
        end
        
        foo = A.new
        foo -> "dummy_argument"
        
Produces:

        ~/test2.rb:2: syntax error, unexpected '>', expecting '\n' or
        ';'
          def ->(arg)
                ^
        ~/test2.rb:5: syntax error, unexpected kEND, expecting $end

But if I substitute the '->' with '>>', the program works and I get:

        dummy_argument
        
Any idea what's going on here?

Running ruby 1.8.6 on Debian unstable.

Many thanks in advance, greetings,
Andrew Green
