Sure. Here's what I've got by reading ruby.core:

1. lambda{} is the same thing as Proc.new{}, except lambda has an arity 
checker plus it rescues 'call' method for LocalJumpError.

2. proc{} is deprecated in favor of lambda{}.

3. Proc.new without an associated block is defined like this:

    def method(&block)
    end

    equals

    def method
      block = Proc.new
    end

    and as I know, matz wants to deprecated this Proc.new usage as well.

Cheers,
Kent.
