In Brand X...

   class Foo

       # <----- this area can't execute statements

     method Bar
       # <----- this area can execute statements.
     end

   end

In Ruby...

   class Foo

       # <----- this area CAN execute statements

     def Bar
       # <----- this area can execute statements.
     end

   end

A class is a block that evaluates from top to bottom, like any other code. Some 
other languages allow that too.
