Subject: Proc#dup?

I noticed, today, that Proc#dup fails ("allocator undefined for Proc"), 
but Proc#clone works.

Is this expected behavior?

$ ruby -ve "p proc { |a| puts 1 }.dup"
ruby 1.8.2 (2004-07-29) [i686-linux]
-e:1:in `dup': allocator undefined for Proc (NoMethodError)
         from -e:1

$ ruby -ve "p proc { |a| puts 1 }.clone"
ruby 1.8.2 (2004-07-29) [i686-linux]
#<Proc:0x402ba958@-e:1>

I'm just used to using #dup. Should I be using #clone instead? I guess 
I've never taken the time to understand the semantic difference between 
the two.
