Subject: TCLTK didn't work with do ... end ??

hi,

i have been played with tcltk and currently i used the button-widget 
like the following:

TkButton.new(root) do
   text 'i am a button'
   pack do
     padx 400
     pady 400
     side right
   end
   command proc {
     puts 'klick'
   }
end

my question is:
why didn't work the 'command proc' with a do ... end?

i've been try this:

TkButton.new(root) do
   text 'i am a button'
   pack do
     padx 400
     pady 400
     side right
   end
   command proc do
     puts 'klick'
   end
end

and then i get this:
tk.rb:23:in `proc': tried to create Proc object without a block 
(ArgumentError)
         from tk.rb:23
         from tk.rb:16:in `new'
         from tk.rb:16:in `new'
         from tk.rb:16

why is ruby saying this?
i don't like bracket and so i'am sooo unhappy about this *snifff*

gentoo
kernel 2.6.5
gcc 3.3.3
ruby 1.9.0
tk 8.4.6
