Subject: Please illuminate how stupid I am re: initialization blocks.

I seem to use blocks much differently from other people and that  
frightens me a little.  (Maybe I'm being really dumb and nobody wants  
to say anything.)

Before I get into what I do, let me define how normal people call a  
block passed in to a method.  They use "yield".  And that's cool,  
that's what yield is intended for.  Their methods tend to look like  
this when they're later put into practical use:

   create_table :users do |t|
     t.column :first, :string
     t.column :last, :string
   end

If I had programmed create_table though, I would have used  
instance_eval, and you'd use create_table like this:

create_table :users do
   column :first, :string
   column :last, :string
end

Am I being really dumb?  Is there something horrifying that I'm not  
grasping?

Thanks for your help!
