But they should do their best to pretend the opposite.
Otherwise the programmer has to mess with their internals
until one day he realizes that a life might be a little
easier without them... :-)

Just take a look at today's discussion threads:
   * Generating a variable in a macro - the core of the
     problem is that record_info is not a normal function.
   * Accessing default values of a record - not having
     this functionality can introduce code duplication.
